World Aluminum Block Main Studs CAUTION

World Aluminum Block Main Studs CAUTION - 08/24/10 04:21 AM

Like the title says, beware.

I Could not achieve a repeatable Torque Value on the Main Studs when Assembling a World Aluminum Block, then 1 Main Stud snapped in half !!
Some had seemed to be "stretching" excessively @ 100ft/lbs just prior to this ?
Upon removal and further inspection, I THEN noticed, that although the Nuts had "ARP" on them, the Main Stud Ends themselves DID NOT ?
Fooled me up until then !

A subsequent Phonecall to ARP, confirms ARP Studs do indeed have "ARP" on the ends.

I Removed the suspected "Chinese" studs, and found they were "stretched" visually thinner in areas on the threads, from the Rec'd 100ft/lb Torque applied.
Mic readings indicated many had indeed shrunk by .030" in Diameter at their weakest threaded points, and were also about to break !

CHECK your World Products Aluminum Blocks, and make sure your Main Studs themselves have "ARP" on the end, NOT JUST THE NUTS !

I will not comment on the phonecall I had with World Products !
however,
I am still unsure how NON-ARP Studs? get mated to genuine "ARP" Nuts as delivered from World Products?

The studs supplied with the World blocks are absolute garbage. I recently had the same issue with several World iron blocks, and not the first one by any means. I could not get a good torque reading, and at first, it actually felt like it was the threads pulling out of the mains. After some testing, I actually set up a height micropmeter to see if indeeed if was what I had susepcted.The " World" studs ( which look like a turned stud, and not a rolled thread) stretched to about .007 , some a bit more! Thats a 1/2" supposed 220,000# stud! THEY ARE CRAP!

I changed all the studs out for ARP, including side studs and problem solved. There were several things that World could have done much better, thats for sure, and to sell those blocks with those absolutely horrible fasteners is a shame.

ARP makes a kit to change them out now.

Dang! I have a new iron World block I'm getting ready to assemble. I'll be checking the studs for the ARP stamp. If not stamped I'll be calling ARP to order a stud kit. Thanks for the heads up..

Re: World Aluminum Block Main Studs CAUTION - 08/24/10 05:22 AM

I guess the question is : Does World advertise the blocks as coming with ARP studs?

Also is the 100 foot Pounds their supplied torque value. If so, then whatever fastener is in that block should work at that torque value.

ANY TIME a fastener has that uneasy feeling when you are torquing it, you need to find out why! All fasteners should come up to torque and feel solid all the way.

Any resolution to this issue from World? I'm supposed to be paying for one here in a few days. NOT cheap. I would also like to know if anyone has anything to say, bad or good, about the cast iron hemi blocks.

Re: World Aluminum Block Main Studs CAUTION - 08/25/10 01:44 AM

For the guys with World blocks, are those putty studs the ones World has in when the mains are machined? I'd be those main journals REAL close....
Posted By: rowin4

Re: World Aluminum Block Main Studs CAUTION - 08/25/10 02:17 AM

Looking at the spec. sheet I got with my aluminum World block it says:Race blocks come with nodular iron main caps with all five caps being two bolt style with cross-bolts on the first four positions. All the main caps use 1/2"-13 studs. Torque spec. on main studs is 100 ft. lbs. with oil and 45 ft. lbs. on the cross bolts

This spec. sheet is generic as it covers both the aluminum and CGI blocks. Now looking in the catalog it says that all complete engines come with ARP internal hardware.
So do they change out the studs to build their crate engines or is this a isolated case? My block is at the machine shop so I can't look but he'll be getting a call for sure, so will World.

i too im putting a world block together. the studs are as described, arp nuts and what ever studs. maybe some one can post the arp main stud part numbers for the world aluminum block. also if any one has arp head stud kit part number for the world aluminum block with eddy victor heads.

i just got two world hemi blocks in,, iron,, first one i thought the studs were worn out cause they were mush when torquing them,, told the guy,, and put in arp... thought they were just used too much

then i got another motor in,, same studs,, has been apart and together twice,, im sure torqued up a few times in mocking up process,, they are soft.... then i read this,,, they just must be all crap

i was going to 105 with moly like i do with all 1/2 studs,, arp studs hit the number hard,,, the world studs either soft or i gave up cause i knew the stud was going to break

Re: World Aluminum Block Main Studs CAUTION - 08/25/10 03:53 PM

After I wrote my HEMI book, I broke a World main stud while assembling an aluminum motor. I used an iron World block in the book and had no issues so I talked to the powers to be and they said they did indeed have issues with their stud supplier. But that was over a year back, and they told me that new blocks would use ARP studs.

Then about 4 months back I had another aluminum World HEMI block delivered and it had all ARP.

one would like to think that in today's world of technology a vendor might very easily track down all the blocks using the junk studs and replace them or at least notify the buyers of pending problems. I guess their mindset is by issuing a recall could hurt future sales. A few related engine failures will cause more than that.

Re: World Aluminum Block Main Studs CAUTION - 08/25/10 04:03 PM

Are we referring to the studs that have the hex/allen socket in the top?

I checked out an iron wedge and I noticed the studs don't have the ARP logo right away...just the allen socket. Haven't really worked with it yet beyond looking it over.

Are these the studs in question? Should they say ARP on the ends?
Will replacing them effect the align bore?

Hi guys, Im Chuck and I will represent WORLD Products. The ARP stud kit is $112.99 at Summit.
Im also the new MOPAR guy here and am currently building an all aluminum 540cu World HEMI.
So I feel your pain with the studs, I even checked
mine, and they are ARP. Any questions you guys have fire away and I will find you an answer.

The boss over here at World is now aware of the problem and has issued a statement to our foundry where both the iron and aluminum are cast. All if any left non ARP hardware is being discarded.
ONLY ARP hardware will be used and to our knowledge that is what was sold. We are currently going through the HEMI and WEDGE inventory here at WORLD to make sure this does not happen again.

Hello Chuck,
What will be done for those of us that bought blocks with the inferior studs? Who pays for the new studs, gaskets, machine work etc. time lost? I paid to have my block align honed with these studs. What happens when I replace those studs with the real ARP hardware?

Hello Chuck and Thx for the response.

When I called Rich Gorle at World to explain the "problem" with the Studs, he was "accomodating", yet seemed unsure himself as to "how" this inferior hardware had got there ?

That, was 5 weeks ago ?

I got big shoulders, been in business along time, I just replaced with ARP Hardware, re-align honed to correct Mains under the "correct" crush, and moved on.

My reasons for posting the "heads-up" on this site about the Main Studs are genuine, and in response from assistence I've received in the past on here, from Guys Like "HEMIFRED", and to extend HIS SPIRIT of helping others avoid potential problems.

Thx for looking into the problem Chuck, I'm sure you agree that "Chinese" Main Studs, MATED to Genuine ARP Nuts, just ain't the way you want your Blocks entering service ?
I told Rich Gorle the same thing 5 weeks back.

Re: World Aluminum Block Main Studs CAUTION - 08/25/10 10:28 PM

Just checked my not yet used world alum wedge... nO ARP on the main studs.
I will assume these main studs where TQ to 100 lbs at the time for line honing and I see no problems with the treads but will replace with ARP just in case.

Posted By: Dragula

Re: World Aluminum Block Main Studs CAUTION - 08/25/10 11:42 PM

What really scares me is, to properly line hone a block, the caps all have to be fully torqued correctly. Therefore tolerances are now off, and they technically need to be re-honed. How can someone have let this go unless they weren't checking them? Seriously, you have size, but also run-out thru all the bores, and true position, and that's all out the window with bolt torque out like that.

The block end of the stud...note the difference on the end of the stud itself....you may be able to see it, but the body of the inferior stud is very " stratchy", you could feel it on your finger nail at each cut of the stud, vs the ARP, very smooth and hard. You will also notice where the shank and the threads meet, notice the rolled threads, the chamfer, and the overall apperance.

ARP on left, unknown on right.

I only have 2 sets of these here now, already spoken for, I can get more fairly quickly if anyone wants them, just PM me.

Hello Challenger340,

Thanks for bringing this potential problem up for me. I got lucky. My machinist has not had a problem repeating or holding the torque values. The studs are not arp's. I am changing to the arp's to keep my blood pressure down. I think because my torque values were correct upon machining the studs can be changed without having to re-machine anything. Now if something happens to the bottom end I can blame my Source crank.lol

That is the very least they should do. I bought my aluminum block before all the "deals" were offered. It was a lot of money for me. I never expected to get cheezy main studs, with quality ARP nuts to disquise them for what they really are.
Chuck comes here to tell us that they have taken care of their existing inventory. Well, maybe that's going to help their future sales, but what about those of us that trusted in the World Products name and spent our $ and got these mystery main studs?
Rant over.....for now!

Hey guys. When this post started. I immediately contact my buddy. Chuck at world. His response was quick and so was the vps. I am sure that world will make it right. I am in the same boat with the studs. The only reason I have yet to fire the motors is I am waiting for lifters. As for the comment about the sale on the wedge spread bore blocks. It wasn't because of the studs I am quite sure of that. Most guys don't want to get into a. 200 spread lifter. I extremly pleased with the service I have received from world. Watch and shoot.

Re: World Aluminum Block Main Studs CAUTION - 08/27/10 04:00 AM

After looking at Coomers pics, ( which kind of look like ARP "finish")it occurred to me that maybe there are 3 versions of this stud. Here is why I make that statement. There is the definate crap stud, as pictured. Then Bobs, which "look" different, but at least more like an ARP. Then there is the stud that I pictured which is definately the newest ARP. When I first found this problem, I simply got individual ARP studs and made up my own "kits" that I needed. In the meantime, ARP came out with a kit, which is what I showed in the picture. I happened to make a call to a buddy of mine who does a very significant amount of World Hemi blocks, and he too had found that there were problems torquing the studs. Now , with all that being said, it is very very possible that a less experienced assembler or builder could have torqued these and never picked up on it. Its one of those " feel" things you get after doing literally dozens and dozens of engines. You may have gotten away with torquing them once or twice, but if your like I am and mock the motor up a few times for fitment, then these things may have even failed over that short of time.

Also be aware, that if if you change out the side bolts for studs, you will have interference with the oil pump ( or could) that will require some attention. Wirh studs, the heads of the nuts will not clear the backside of the oil pump.


I dont know the answer, but I do know the fix. Hopefully Chuck can step back in and explain. Whatever the case, there definately WAS a problem, but was it every block sold? Who knows.

Called my machine shop to check the main studs on my World Hemi block . No visible ARP markings on the ends. They'll order new replacements. Should I bill World ?

What's the word Chuck? Haven't heard anything from you.




CHUCK has his email listed in his profile. I would think by now it would be overload with questions.

My hemi block should be here early next week and you can bet that I'll be checking the issue ASAP.

Gentlemen,

I'd like to introduce myself. My name is Paul Kaufman. I have worked for World Products as a technical representative and engine builder for approximately a decade. I have been building engines professionally for the better part of my life with over 40 years experience in both the private industrial sector and performance speed industry. I have been asked to express my opinion ( and that of World Products ) regarding concerns some of you may have with the main studs utilized on the Mopar iron and aluminum Hemi and Wedge blocks manufactured by World Products. World has manufactured several thousand of both the iron and aluminum blocks in the last few years and recently we have heard that some of these studs have failed when torqued. I have personally assembled many of the Hemi and Wedge engines at World Products, and have not had any issues. I would love to be able to say that there are many torque wrenches that are being used that were manufactured in third world countries and that is the problem, but that would be unfair. World Products does not manufacture studs nor do we import inexpensive hardware from China. The studs used on the Mopar iron blocks are to Mopar's engineering specs and our engineers determined those studs to be of sufficient quality for use on World Products aluminum blocks as well. These studs are not ARP. More recently World Products chose to switch to the ARP brand studs, not because we found them to necessarily be better, but to align ourselves with the hardware being utilized on our Chevy and Ford blocks. I would like to point out that over the years I have experienced failure with hardware manufactured by ARP, but grab another one and move on. I have also experienced a rod breaking or a lifter failing, all from big name brand manufacturers, but that doesn't mean the sets of parts were all defective. The point is sometimes rods break, lifters fail and bolts and studs stretch, break, threads gall, etc. It is the nature of metal objects that have been cast, poured, machined and manipulated that a small percentage will fail, regardless of who manufactured the item. If you find one defective stud that does not mean all the studs are bad. As with most manufacturers, World Products has a warranty policy. Should you find any defect in any of World Products parts or components within one year of purchase simply contact us and we will be more than happy to exchange that defective part. If you would like to change out your hardware to a complete set of ARP studs, you can purchase them from your local ARP dealer or retailer. The caps are located by ring dowels and block registers. The line bore will not be affected. The torque rating on the ARP studs remains the same. Thanks for your time, Paul

IF you check the cheap studs provided, and those inspected by knowledgable engine builders on this site, you will read the post that stated the threads on the CHEAP Studs were scratchy. Sure sign of low budget inferior studs. It is too bad World has decided to let the studs stand and not be willing to replace them as a whole.
I am REALLY GLAD I saw this post as I have been bidding on an aluminum Hemi block from World on ebay. I will not be going thru with this in light of this response from World. Such BAD Publicity could have easily been corrected by simply replacing the studs or offering, at the very least, to split the cost of replacement to a quality stud set. Just really disappointing. I wonder what there response would have been if it were a bunch of there beloved Chevy blocks that had issues. They have bent over backwards to correct the issues in the past for Chevy customers. Boy, Just disappointing! I suppose Indy or KB will get my money now.

Well put Paul,we have seen alot of issues resulting from incorrect torquing methods(torque values or wrong lubricants)as well as bad stud installation or application.We usually make the correction and move on.However even with the dowel rings that locate the main caps(similar to rod caps)the different clamping loads of different fastners would raise the concern for distortions(no mater how small) and would warrant at least checking or honing the line bore for perfect or "near" perfect alignment and fit.I would never change rod bolts(even if the same replacements) without checking or resizing the rod.May I inquire who manufactured the studs that came with the block?Just my opinion Respectfully Bob

Re: World Aluminum Block Main Studs CAUTION - 08/27/10 11:24 PM

Well, as some of you know I just grenaded my new World blocked 572 a couple weeks ago and destroyed the block. My engine builder called me Monday and during the conversation he said the main caps had been walking and galling pretty badly. He wondered if I was running bad gas or way too much timing but that's not the case. The timing never went over 33 degrees this year and I run K&S 120 (114 octane) race gas.

Now I suspect my motor had the low quality studs in it also. I can't ask him to look at them until Monday but I bet that's the deal.

I need to buy a new block and now I'm wondering what to do. A lot of you here on Moparts say to go with KB but there's some serious drawbacks to that block, at least for my particular setup.

well you heard the man, if the cheap a$$ stud fails within one year while you are going down the track and you have massive damage. simply return the one broken stud and they will replace it.

Now if you were one of worlds chevy or ford customer you would never have gotten the cheap stuff.

I am sorry i every bought a World block, i should have stuck with someone that specializes in mopar engines, not someone that added it to their product line as a after thought.

Re: World Aluminum Block Main Studs CAUTION - 08/28/10 12:16 AM

Don't take my statements the wrong way guys. I'm not blaming my engine failure on the main studs, whether they're ARP or any other brand, or even on the World block itself. I had a rod break, plain and simple. No fault of World Castings.

I'm just wondering if the studs have anything to do with the main cap walk and whether I want to spend my money on another World block.

Re: World Aluminum Block Main Studs CAUTION - 08/28/10 12:30 AM

I never saw anything that World said their blocks were supplied with ARP main studs. And they meet the MP specifications which these were made to. Did I miss something?

I did see someone say if you find a defective part during assembly to let them know and they will take care of it.

I think the lack of ARP studs is disappointing, but I don't see anything they did wrong.

there's no excuse on a 4,000 block to use anything but 1st class studs. Stevie Wonder could have seen these looked like junk by the finish.Where was quality control ? What will be done about those who lost an engine ? blame their torque wrench ?

John, I did call World today and I talked to Paul. He told me that he was going to post a response to this thread today, as he had read it.He also said he would have someone else do it as he doesn't have time for forums! Maybe he changed his mind, maybe not.
They are doing nothing about the studs, unless you break one in a block that is within the one year warranty. he feels that the studs furnished are good.
He also said that some of the guys here try to make engine building be rocket science, and it isn't.

Re: World Aluminum Block Main Studs CAUTION - 08/28/10 01:44 AM

first off I have no dog in this fight since I run a lowly small block but I do remember when World came out with these that every one raved on the fact that there was another option and that World had improved a number of things over all the other blocks such as oiling and 2 bolt patterns for different bell housings and such.
Now there is a problem with what seems like a few of the many blocks that was sold and now World is crap I think that some would say that's unfair.
We all have heard the many horror stories about Indy but we still buy there stuff but we have it gone over by someone we trust so they can correct any issues that there is sure to be I just wonder how this is that much different.
If i purchased a new block and saw that the studs where nor ARP I would address that right then not later and all ARP stuff has ARP right on it so there is no guessing.

Re: World Aluminum Block Main Studs CAUTION - 08/28/10 02:22 AM

I'd like to introduce myself. My name is Paul Kaufman. I have worked for World Products as a technical representative and engine builder for approximately a decade. I have been building engines professionally for the better part of my life with over 40 years experience in both the private industrial sector and performance speed industry. I have been asked to express my opinion ( and that of World Products ) regarding concerns some of you may have with the main studs utilized on the Mopar iron and aluminum Hemi and Wedge blocks manufactured by World Products. World has manufactured several thousand of both the iron and aluminum blocks in the last few years and recently we have heard that some of these studs have failed when torqued. I have personally assembled many of the Hemi and Wedge engines at World Products, and have not had any issues. I would love to be able to say that there are many torque wrenches that are being used that were manufactured in third world countries and that is the problem, but that would be unfair. World Products does not manufacture studs nor do we import inexpensive hardware from China. The studs used on the Mopar iron blocks are to Mopar's engineering specs and our engineers determined those studs to be of sufficient quality for use on World Products aluminum blocks as well. These studs are not ARP. More recently World Products chose to switch to the ARP brand studs, not because we found them to necessarily be better, but to align ourselves with the hardware being utilized on our Chevy and Ford blocks. I would like to point out that over the years I have experienced failure with hardware manufactured by ARP, but grab another one and move on. I have also experienced a rod breaking or a lifter failing, all from big name brand manufacturers, but that doesn't mean the sets of parts were all defective. The point is sometimes rods break, lifters fail and bolts and studs stretch, break, threads gall, etc. It is the nature of metal objects that have been cast, poured, machined and manipulated that a small percentage will fail, regardless of who manufactured the item. If you find one defective stud that does not mean all the studs are bad. As with most manufacturers, World Products has a warranty policy. Should you find any defect in any of World Products parts or components within one year of purchase simply contact us and we will be more than happy to exchange that defective part. If you would like to change out your hardware to a complete set of ARP studs, you can purchase them from your local ARP dealer or retailer. The caps are located by ring dowels and block registers. The line bore will not be affected. The torque rating on the ARP studs remains the same. Thanks for your time, Paul


Wow, has this taken an interesting twist. Let me first explain my position. I have no reason, no hidden agenda, or no ill will against World Products. Have no reason to. I had talked to Paul quite some time ago before PRI and we discussed their engine builder program. It wasnt soemthign that would work for me, so I chose not to participate, as the bulk of what I do is Mopars, and they just didnt have enough other products to assist me in my business. Paul was fine to talk with, and they were at the beginning stages of trying to build up their engine builder program. I alos know that they were NOT building a lot of Mopars out of their shop. I am sure they will say different ( as kind of already stated) , but from one of their employees, in a direct phone call, they simply were not.They are obviously far more concerned with building Chevies. ( and that is fine, I understand).

To come on here and say that we are using cheap offshore torque wrenches, think we are rocket scientists, dont know how to properly torque a main bolt is absolutely appauling.When I say these studs were junk, I am telling you, they were junk. I still have some of them left, so now the thought process should be to go have a stud inpsected at a metallurgical lab, and I bet I can pre-write the diagnosis.

I had another well known and respected builder in my shop when this first came to light. He saw it, felt it, and experienced. So as not to think I was crazy, I took the block to another shop who has a jig bore mill, as I was ready to install Time Sert inserts into the block, as it seemed like the threads were pulling. Although they werent engaging smoothly, I finally realized the threads werent the problem.Once I set up a indicator, and then torqued a ARP stud, and then a World stud, it was VERY clear what was going on. I then inspected the studs closer and it was very evident. My question is now, since they wanted to be better aligned with what they use for their Fords and Chevies, why didnt they just use ARP from the start ?Like they do in their ither engines. I can guarantee you one thing, if Bill Mitchell was building THIS motor,for himself, he wouldnt have used these studs.As you may now realize, I had a ton of time wrapped up in this, making it right.

I am not on a witch hunt. I am merely explaining what I have found. It is truth. Period. I am experienced enough to know the difference. Those of you that know me, know that I dont watse time on the internet in " internet drama" and " internet bashing". I prefer to either just handle things myself, or call the manufacter.The problem is, like many engine builders, your under the gun, have a lot of pressing schedules, and just handle it yourself.I didnt feel from previous experiences with World,( other fellow shops) that they would handle the situation at all. We have now experienced that first hand.

I have had World Hemi blocks, World Wedge blocks, ( cast iron) but have not used a World aluminum block. Cant say anything about those, havent touched one.

Since we are the inexperienced ones, then why would I need to finish milling out several of the water passage holes in the block, repair the large step that was left on the block by the rear main seal area, so bad the retainer wouldnt fit. ( another expense for me)and fix the dowel holes in the decks? I did re-align hone this last block after changing the studs. I simply was not going to even risk anymore issues. Its going in a 7 second dragster, so I didnt want him driving over the crankshaft at 180mph.

In closing, I think their answer is poor. They used something ( dont know whos) other than ARP to save money. I can hardly believe its anything else. ( and that is ok as well, but they should have been of decent quality).I will agree that ANY manufacter can have an issue. ARP, World and so forth. It happens. Its how they handle it that matters. I think you just got a taste of " how they handle it". Basically call us incompetent, internet drama hill billies. Another shame.

Re: World Aluminum Block Main Studs CAUTION - 08/28/10 02:37 AM

Well not much of a dog in this hunt, I have built three of the World block engines however. So here are a few things to ponder. First off it says nowhere that they use ARP studs correct? So I do not see any issue there. The blocks I have done were all fine, had no issues with stud torque and do not recall any issues with them. However, why ARP nuts but not studs? Seems almost borderline shady, I imagine most folks see the ARP nut and ASSUME the stud is as well. Well you know what they say about assuming anything. I also own a shop and go above and beyond on almost a daily basis to make customers happy. But that is my choice. Seems World does state they will replace any fastener found to be defective within its warranty guidelines. Sounds like the automotive aftermarket manufacturer thing to say, most woudl reply the saem way.

I think World is kinda getting thrown under the bus here. Not totally undeserving however. Seems maybe there was a slight deception going on with the nut/stud deal. But knowledgeable guys know about that issue. Blaming any failure on the end user is well kind of gutless IMO. FWIW I had an issue with a World block. It was a BBC Merlin block. Had the oil gallies drilled into the water jackets. They took care of it and sent out a fresh new block to replace it and told me to keep the bad one. It was subsequently fixed and it still in use now.

SG why is the KB not an option for you? I run one and it works great...

Why do the studs only go halfway through the nuts? If that cap is all the way down (which it appears to be) those studs are at least 3-4 threads too short, no matter whose name is on them.

Although I doubt that World will miss the business, it is looking like their response may cost them more that the cost of a few sets of main studs.

Maybe it will mean a little more business for KB.

Re: World Aluminum Block Main Studs CAUTION - 08/28/10 02:53 AM

Where is the "foot in mouth" smiles at?? LOL
Of coarse it was the torque wrench, what was we thinking..
So those bolts were just as good as ARP bolts? Even though World has decided to replace them now with all ARP fasteners just like Ford and Chevy? Why order or deal with them in the first place if you have a contract with ARP for your main supplier?
Bottom line
Money
Money
Money
Money
First let me say that My bolts had NO torque problems, there where cycled at least 3 times minimal. Once when from the factory, I actually checked them when I broke them loose with my torque wrench. Then I slapped in some bearings and measured ID for bearing clearance with the dial bore gauge. Then again during final assembly.
My torque wrench is made by Proto..Its probably 15-20 years old....I check it 2-3 times a year for accuracy. The Snap-On man has a checking tool mounted in his truck..Just takes a few seconds to verify readings...
Let me say its pretty lame to start crying about inferior "China" made torque wrenches, that by chance some might use...
Im just saying this web site reaches people on a global level, and news about bad company ethics and poor parts will spread faster than a snotty nose at the local day care.
Especially In the days of this economy when there is several diff choice of the same part...for the same money..

Re: World Aluminum Block Main Studs CAUTION - 08/28/10 02:59 AM

To clarify, I use Snap On torque wrenches, and actually do calibrate them. Calibration sticker is on them all.I had access to a precision tool and die shop where my brother worked, and he would also certify my mics.Far from Chinese quality.

I also have a KD dial type torque wrench, and it is very accurate.

Re: World Aluminum Block Main Studs CAUTION - 08/28/10 03:24 AM

Reading through there catalog again and found a interesting paragraph on there chevy short block assembly. "Also available are premium quality ARP fasteners, as used in complete World engines" So I guess the spec. sheet I got with my block was correct it states main studs 1/2"-13. And if I would have bought a complete engine it would have had ARP studs,maybe.
I should have read the chevy spec. sheet and read between the lines also. I'm just changing mine out before machine work just as Paul would say to sleep better at night. $ 125. bucks down but thats just a drop in the bucket for this build.

Hi guys, Im Chuck and I will represent WORLD Products. The ARP stud kit is $112.99 at Summit.
Im also the new MOPAR guy here and am currently building an all aluminum 540cu World HEMI.
So I feel your pain with the studs, I even checked
mine, and they are ARP. Any questions you guys have fire away and I will find you an answer.

The boss over here at World is now aware of the problem and has issued a statement to our foundry where both the iron and aluminum are cast. All if any left non ARP hardware is being discarded.
ONLY ARP hardware will be used and to our knowledge that is what was sold. We are currently going through the HEMI and WEDGE inventory here at WORLD to make sure this does not happen again.

CHUCK




Does any one have the part number for the ARP main stud kit for the world block? I have a new set of ARP studs for an OEM 440 block that I was going to use, but the junk studs out of the world block are longer, so I don’t think the ARP studs I have will work. The shop that is machining my world block told me today that the world studs torque to 100 foot pounds and felt solid. The line bore was dead on. He said they think the studs will be okay. He did say there were other problems with the block. The lifter bores and oil pump shaft busing were both under size and had to be honed. No big deal there. I’m not going to gamble on the world studs. I called Summit and they don’t have a listing for the ARP kit that ol chucky boy at world claims they have for $112.99. Hay chuck, how about giving us a part number? Better yet why doesn’t world man up and stand behind their product and replace the junk studs they installed with ARP studs?

These studs are not ARP. More recently World Products chose to switch to the ARP brand studs, not because we found them to necessarily be better, but to align ourselves with the hardware being utilized on our Chevy and Ford blocks.




statements like the one above remind me of campaign promises and legalese doublespeak. utter nonsense comes to mind. i'd like to be more positive, but having witnessed the stud problem firsthand, all i can say is that it's a real problem.
World was already "aligned" with ARP but obviously chose initially not to use the ARP product for some reason. one can only guess the reasoning behind that move and the more recent shift towards ARP.
i wonder how long it'll take for warranty replacement of the defective studs?
I'm happy World (or anyone for that matter) is making Mopar engine blocks, but i've been on the recieving end of thier customer support more than once, and it ranked right up there with lackluster. best of luck to those affected.

Definetly would see about putting more commonly(ARP) performance studs in the buids.....

Guess Mopar was nice enough to me to use somewhat decent bolts in my R3 mains....held up to 2-300 more HP than most of yalls big blocks

Though have stepped up to ARP suds now.

Al, my car's all set up for the World Block. I have engine limiters (struts) that come off the factory motor mounts. The KB block has no motor mounts.

Also, I use the Chevy bolt pattern on the World block to mount the 'Glide. In order to use the KB block I'd need to install new engine limiters somewhere and buy a new adapter kit to mount the Glide to the Mopar pattern on the motor.

I think the KB block oils the rockers differently also? Not sure what else might crop up??

I just don't want to re-engineer my whole car in order to change to a different brand block. Not to mention the added expense of the more expensive block, adapter kit, new engine limiters, machine work to oil the rockers, etc etc.

Can you imagine that? He would have paid whatever small additional cost there might have been to get a premium main stud like he puts in all his other much less expensive engines!
Are the Ford and Chevy blocks that get the ARP fasteners more expensive than this HEMI block?

It states in the catalog:ALSO AVAILABLE ARE PREMIUM QUALITY ARP FASTENERS AS USED IN COMPLETE WORLD ENGINES . I would take that to mean you could up grade when you ordered. This was listed for a chevy. No where does it say that on Hemi or wedge blocks. Just 1/2"-13 studs .

Don't know with the wedge version, but on my hemi I had it ordered with motormounts which, now it's in my racecar, I use for limiters too. As far as oiling I just use some '64 alloy heads with stock rochers and stands without any oiling problems. Just had to use external oiling but wanted that anyway. Had zero to complain about my KB.

Re: World Aluminum Block Main Studs CAUTION - 08/29/10 03:07 PM

It seems I may have stirred up a bit of a "sh**storm", with my well intentioned CAUTION post originally ?
That was not my intent, however, given subsequent responses, and the prevalence of similar experiences from others finding this Inferior Block Hardware and the Main Stud "Failures" @ Load, I would like to clarify a few things.

* I took issue, with the Mating of genuine ARP Nuts, to NON-ARP Studs in the Block as delivered from World Products.
I, like others on here it seems, find this "questionable" product practise ?

* I also take issue to references from a World Representative, of Foreign made Torque Wrenchs as being an "Unfair", but nonetheless STATED, potential cause for the Stud Failures ?

* Lastly, I am somewhat peeved with further references that World "Engineers"?, have determined "those studs to be of sufficient quality".

In Response to the above;
I will be shipping all the Studs in question, which I feel are defective, for a complete Mettallurgical Analysis, both Destructive Tensile & Non-D, Rockwell, etc., etc., full spectrum.

I am lucky enough to be located Geographically in the Oil & Gas Capital of North America, with some of the most reknowned Industrial Engineering Infrastructure & Testing Facilities in North America close by.
They Test "metals & fasteners" all the time, on everything from Blow-out prevention Fasteners to Sour Gas Well Hardware.
Remember the recent Gulf Oil Spill Fiasco ?
We produce more Oil here in 1 Day, than that entire LEAK spilled in the Gulf!

My point being,
stay tuned,
I WILL have a Full Report on the Studs, and their compliance with any "known" Industrial Standards ASAP.
It will some take time, I will report back when completed.

Personally, If this had to go beyond my original CAUTION post, I would have sincerely hoped, and expected, that World Products would have stepped up, and indicated knowledge of a "suspected" supply chain management problem involving Wrong Main Stud hardware, and asked for imput from those affected for some kind of remediation effort ?
Just Good Business in my opinion only.

I sincerely hope, that the Stud Analysis when completed, is NOT akin to a rating of the Cheapest poor quality fasteners available, and NON Compliant with any "known" Industrial Technical Grading ?
THAT, would sincerely compromise any Findings by World "Engineers" of Fastener suitability ?

I Thank You for your time, and apologize to this Boards Onwers, for using up valuable Bandwidth, on what should have been a NO BRAINER Caution report.

I am not here to defend his post. A few others have made mention that we were accused of using junk Foriegn made torque wrenches but read his post again. He never accused anyone of that if you read it as I did he was not in any way going to lay that as being the cause.In fact I think he was disregarding it as possible and unfounded excuse ,

It's my understanding that these blocks were built to replace the MP blocks. My alum. block says MOPAR on it.(see pic) So the World Products tech was saying that MOPAR specs were complied with for the main studs.I would be surprised if these studs will meet OEM requirements if so many are stretching or breaking. It would be interesting to know what those specs are.

Re: World Aluminum Block Main Studs CAUTION - 08/29/10 11:59 PM

Well, It seems bad news always travels fast! I shipped 3 of these aluminum blocks to Australia earlier this year. Just checked one to find the no name main studs with ARP nuts and cross bolts.It seems to me incomprehensible that World Products are prepared to comprimise the integrity of these blocks and its future reputation to save perhaps $20 or $30 in production costs. Even if the ARP studs were offered as a $50 upgrade on the block purchase I doubt anyone would opt for the no name studs if they were given a choice. I, like others, thought they were fitted with ARP fastners based on the nuts and cross bolts.
AS TO WORLDS REPONSE:
I personaly work in the retail industry here in Australia and to me this could potentialy be a public relations nightmare for the company. In retail we work on the theory that every customer that has a percieved bad experience potentially up to 100 people will here about it directly or indirectly.
From World Products point of view this should be about damage control to there brand. It doesnt matter if their engine builder/representative vouches for the integrity of the studs we are past that now. More than one other competent engine builder has raised legitimate concerns with these studs along with the perception of customers who feel they have been deceived. World Products themselves by changing to ARP fastners in all future blocks only reinforces this perception. We all make mistakes in life knowingly or unknowingly and from a buisness point of view its how you choose to deal with the problem. In the interests of customer relations I feel World Products should offer anyone who purchased a block already and is uncomfortable with the studs a set of ARP free of charge. I hope someone at World Produts reads this post and gives it some consideration.

IMHO if going to an after-market block is to be considered an upgrade, to our performance engines, (and I bet World wants us to see it as such) then why would we spend that much money to upgrade to a block fitted with fasteners that could unravel it all?
Consider the upgrades folks here put into the main caps on factory engines, alum main caps, girdles, etc. It is obvious to me we would want the best fasteners in our new after-market blocks. Adjust the selling price accordingly. The Mopar blocks are already more $ than Ford and Chevy.
But wait! They knew it! They did put ARP nuts on them!

After all the problems I had with my first world aluminum block and now this I will never buy another product from world. I also know for a fact that when I assembled my engine the main studs had no markings on them. So as of this time even after 150 passes my car will be parked until the engine gets torn down.

In Response to the above;
I will be shipping all the Studs in question, which I feel are defective, for a complete Mettallurgical Analysis, both Destructive Tensile & Non-D, Rockwell, etc., etc., full spectrum.




My point being,
stay tuned,
I WILL have a Full Report on the Studs, and their compliance with any "known" Industrial Standards ASAP.




This is great!
I anxiously await your findings!

FWIW I got this from Yellow Bullet,


The studs were never arp. I worked on the original hemi/wedge blocks from world and I pointed out to Bill Mitchell about the studs and he did not answer my questions. I would put the main studs in finger tight and they would still feel loose. You could wiggle them with your finger tips. I never did like them. Kenny.

I see now that the cross bolts on my engine are ARP. With the stud nuts saying ARP, and the cross bolts being ARP, why would we have questioned the studs manufacturer ? An easy way to deceive us.
I would have gladly paid up front for the ARP studs. Like said, it would have saved a bunch of time and money in the long run.

Bolt manufacturer's aside, has anyone replaced them and remeasured the line hone?

If the bolt stretched when they were tightened before boring, when they are replaced, the size & run-out will be different. I am just curious if anyone has checked.

Side fasteners = ARP, main stud nuts = ARP, main studs = One Hung Low foundry, Taipei. The studs are going in the trash and I'm biting the bullet for ARP studs. What a bunch of cheap jerkoffs. Other than the idiot corner cutting, it looks like a nice piece.

I have a world iron block that was purchased in the Fall of 2009 and assembled by Dwayne Porter and subsequently dynoed (720hp/720tq)...it's a pump gas 572. When this post came up i spoke with Dwayne and he stated that the main studs on mine torqued up fine. He stated that the studs are good and not to worry about it. This is not a full on effort and if it were i would have better hardware in there anyway....including the crank & rods.

Perhaps World has changed suppliers in the past year ? That could certainly account for the soft metal fastner that a few of the reputable engine builders have described.

Thank you challenger 340 for bringing this potential problem to my attention,my new world block was prep by Ohio crank.I also saw ARP nuts and thought i had the best studs also,but as pointed out who knows what we have.I have checked these studs with thread mics and the major dia and pitch dia was perfect that is on the long studs,that was not the case with the 2 shorter #5 position these where streched as you had found .the pitch dia and major dia are way under tolerance this happend in the area of thread that did not enter the block threads.This indicates to me that this is a very bad thing.As i said before ARP only way to go.

Re: World Aluminum Block Main Studs CAUTION - 09/01/10 02:59 AM

I still believe there are motors out there that people simply didnt " catch" this problem. Between inexperience, in a rush, "thinking" it didnt feel right but using them anyways, not knowing, or lastly just not caring, they are out there.There seems to be some that may be different or ok, just dont know when.

It would have been very easy for some to just use them and not really know what they were experiencing.The design of the bad studs is just that, bad. No comparison to the rolled ARP threads, undercut, chamfer etc, not taking into account the actual tensile strength , hardeneing or overall soundness.

I have already changed out several "studs only" for the mains, as well as gotten new complete kits for members here and my own clientelle. I think if nothing else, they all are resting better. The " bad" ones really are BAD.

Re: World Aluminum Block Main Studs CAUTION - 09/01/10 03:43 AM


These bolts arent ARP. Like I say I never had any issues with torque settings. At this point, its too late. I dont plan to take the engine out of the car now that its running, take it apart, replace the bolts and hone the block if needed. I had no torque problems during assembly, the bolts did get cycled 3x's or more.I will replace the bolts at a later date during a routine freshening....I hope...

Re: World Aluminum Block Main Studs CAUTION - 09/01/10 08:16 AM

OK, I have done some research on these main studs.If you already have the ARP cross bolts and ARP nuts on the "no name" studs, you can replace the main studs with ARP #AR4.620-1LB X 8 and #AR4.400-1LB X 2. I did a google search and vendors have them for aprox. $5.50 each.

Re: World Aluminum Block Main Studs CAUTION - 09/01/10 02:18 PM

That is correct, and your part numbers are correct. I posted way back in the post the part numbers for new stud kits. I dont think the side bolts are of any issue.

Everyone can make up there own mind, make their decision based on whatever it is thats important to them, and move on. I am burying this dead horse from my perspective, because their still seems to be people that dont believe this is an issue or dont believe the findings. We all have our own opinions and choices.

Teamx thanks for the part numbers, I ordered the studs online and they will be shipped to my door for under $55. I can’t believe all the ill will that World is willing to endure over $50, this has to be one of the dumbest business decisions I have ever seen.

Re: World Aluminum Block Main Studs CAUTION - 09/01/10 10:12 PM

If a guy didn't know any better, he'd think the stud part numbers must be wrong because World Products lists both studs being compatable with two different Chevy blocks but not anything else...

http://www.worldcastings.com/images/ARP%20WORLD%20MASTER%20KIT.pdf

So, as it turns out they had the right studs the whole time.

Per R--, the machine shop (neither owned nor operated by World Products), proper stud torque is 85 ft lbs with moly. This is the torque spec used when the blocks are align honed. The machine shop has never broken a stud at 85 ft lbs, ever. However, World's info from 4 years ago stated the torque spec is 100 ft lbs with no lube recommendation, somehow that got carried over to I sheets and is in the process of being corrected.

Per the machine shop, the supplier of the no name main studs is (guess who?) World Products.

Shifting the blame to "the foundry" earlier in this thread was pretty funny. A foundry doesn't use any fasteners at all, so how was it their fault? And the foundry mark on my iron block is "DF" (with a backwards "D".....I'm pretty sure the Da---- Foundry isn't owned or operated by World Products either, and I'm pretty sure they are using Chrysler's million dollar tooling to produce the engine blocks we are discussing here.

So this all leaves me to wonder:

What exactly was the point of using ARP nuts, but nothing else? Was the belief generic Mc Master Carr hardware is good enough for us Mopar guys, but only beloved Chevy customers get the GOOD hardware? Or was it since the block says Mopar on it, the assumption was people would just blame Mopar for the garbage hardware? I think we can all see how that deal worked out, and I think we all know who's at fault here.

I can't share any more of the research I've done on this topic, however I've looked into it far enough to see that it stinks to high heaven.

I know where I'll stand when it comes time to weigh in on this supplier at work.

Re: World Aluminum Block Main Studs CAUTION - 09/02/10 12:58 AM

Just got off the phone with my engine builder. He looked at the studs out of my World block and they're not ARP. He did say that they torqued OK when he assembled the motor but we both think the cap walk I've had could have been partly caused by the studs.

So whatever I end up doing for a new motor, it's gonna have ARPs.

Re: World Aluminum Block Main Studs CAUTION - 09/02/10 01:21 AM

I think you might have something there. A malfunction of all the people complaining on here. I will admit I have not read every post but I bet you guys are burying world over something that is not even a valid problem on their part.

My MOPAR R3 Race Block was supplied with normal production type grade 8 Bolts and mopar would not send it out like that if it would automatically blow up using the supplied hardware. In that case I would use oil as lube and torque to factory specs or the specs in the instruction sheet. Common sense. If I wanted I could upgrade to ARP hardware and use more clamping load and re-hone the mains.

The ARP studs are 200K tensile strength and I am sure the supplied fasteners were not that strong. "BUT", that does not mean that they are junk or chinese made etc. A lot of you guys should be ashamed talking like that.

I am fairly confident if you built your motor with the supplied hardware and followed the instructions your motor would be fine. If you are going to build big power then upgrading the hardware is your descision as it is with ANY engine build.

that's a strange way of looking at things. World supplied the block, the fasteners and the spec sheet. are you suggesting that every person that has had issues with the supplied studs either over torqued them, or somehow made them magically stretch like silly putty why???
i guess the problem is now solved. nobody knows how to properly assemble an engine. amazing...

I have read all posts on this thread and I can´t see anything wrong with the critic.
Most mopar BB suffers from bad cap walk, even at low hp so these studs are probably one of the worst ones to downgrade quality on.
If you could use even higher quality material like in the 2k2 rod bolts, and the torque could be increased. It should help reduce the cap walk.
World did just the opposite

I have one that was the most consistant and trouble free 572 B1 motor I have built to date. I had my machinest check the studs and they were ARP, so we put it together and I'll be using it next year. It makes 1000+ so, I wouldn't be afraid of them. And I think the other guy that windowed one was 66CHARGER, or something in Oregon. That had nothing to do with the block.

Gentlemen,

I'd like to introduce myself. My name is Paul Kaufman. I have worked for World Products as a technical representative and engine builder for approximately a decade. I have been building engines professionally for the better part of my life with over 40 years experience in both the private industrial sector and performance speed industry. I have been asked to express my opinion ( and that of World Products ) regarding concerns some of you may have with the main studs utilized on the Mopar iron and aluminum Hemi and Wedge blocks manufactured by World Products. World has manufactured several thousand of both the iron and aluminum blocks in the last few years and recently we have heard that some of these studs have failed when torqued. I have personally assembled many of the Hemi and Wedge engines at World Products, and have not had any issues. I would love to be able to say that there are many torque wrenches that are being used that were manufactured in third world countries and that is the problem, but that would be unfair. World Products does not manufacture studs nor do we import inexpensive hardware from China. The studs used on the Mopar iron blocks are to Mopar's engineering specs and our engineers determined those studs to be of sufficient quality for use on World Products aluminum blocks as well. These studs are not ARP. More recently World Products chose to switch to the ARP brand studs, not because we found them to necessarily be better, but to align ourselves with the hardware being utilized on our Chevy and Ford blocks. I would like to point out that over the years I have experienced failure with hardware manufactured by ARP, but grab another one and move on. I have also experienced a rod breaking or a lifter failing, all from big name brand manufacturers, but that doesn't mean the sets of parts were all defective. The point is sometimes rods break, lifters fail and bolts and studs stretch, break, threads gall, etc. It is the nature of metal objects that have been cast, poured, machined and manipulated that a small percentage will fail, regardless of who manufactured the item. If you find one defective stud that does not mean all the studs are bad. As with most manufacturers, World Products has a warranty policy. Should you find any defect in any of World Products parts or components within one year of purchase simply contact us and we will be more than happy to exchange that defective part. If you would like to change out your hardware to a complete set of ARP studs, you can purchase them from your local ARP dealer or retailer. The caps are located by ring dowels and block registers. The line bore will not be affected. The torque rating on the ARP studs remains the same. Thanks for your time, Paul




so your saying to go pound sand pretty much!




sounds like it!
