I need to look around if i have a pick of the cnc work on mine they take out a lot.. i weighed mine it was 128Lbs after the cnc work. Like i said looking at the 2 you can see how much stronger the Indy is..but thats just looks

---

Yea
This World Hemi Block is porky..Damn thing weighed 338 LBS, thats with NO freeze or galley plugs...I think I blowed a O-Ring out moving it around..

I think first thing is to compare the world race block to the indy block. Although it doesn't change much in the strength factor it has some better options like bushed lifter bores and dual bell housing bolt patterns. Indy has a larger skirt and the fifth main is cross bolted.
Some peoples opinion may be the indy block is stronger but unless you were in the design room it's only speculation. Looks can be deceiving. Something like the quality of the block material can throw that theory out the window
Most will never run either block close to their limits

---

The only problem with Indy is the people at Indy .. I will stop there. as for the lifter bores being bushed thats just machine work. just look in that area.. The Indy wins hands down with some of the high spring Psi ran.. some are close to or over 1000 psi over the nose. the indy is stronger in that area. look at the front 1 cylinder side lifer bores ..As for the Dual bell pattern thats nice but most aftermarket cases come with a Mopar opt. again No biggie.. Look at the main webbing. All I did was post this to see what people have seen and there thoughts .. were not in on the Design..... were the end users.. BOB when I do buy another block.. its thru you .I can't deal with the Edit over at ---Y..

Unfortunetly most of the ones I've came across are already 4.50" I was hoping more would show up before I buy a new Iron World Block.

That's what sleeves are for.And for WV Charger,BGR guys will be forming a line for you and Pap.

No pissing match here.Indy has a great bunch of dealers and WDs right here on the site.

Here is a thought at what I see. The indy lifter bore area looks superior to the world but when you look underneath how the skirt area is so much larger than the world block, is all that material needed to keep the block from moving around?
All that material is in the valley area for a reason. .
If the lifter bore valley was a true problem than world would have made it beefier.

The tight skirt area is a concern with stock and after market blocks.This is an area that traps oil around the rotateing assembly and cause a lot of oil to be thrown on the cylinder walls and cam.This area is the cause of some of the loss of oil pressure at the big end.The Indy wide pan blocks allows the oil to migrate further away from the rotateing assembly and returning to the sump quicker.

We a constantly learning also,and are glad to pass on what we learn.As far as the blocks we get from Indy,they are quality and any changes we make are our decisions for our or our customers specific needs.As a end user or representative to the end user we are responsible for the products final state.We some times supply unfinished blocks to other builders.With that being said,since we don't live in a perfect world and crap is known to happen,we stand behind our work and Indy stands behind us on their product.What few and minor issues we have had in our almost ten year relationship has always been resolved satisfactorly and professionally.I don't see the issues of customer service that most complain of.From Carrie,Jim,Sam,Ken and Russ at Indy I can only say that they are friendly,curtious,helpful and professional in our busniess relationship.They meet our criteria of a great manufacture and supplier of products and BGR meets their criteria for a good customer,we use their products and pay our bills.I don't get any better than that.

just askin but how can anybody look at a block and say its stronger! it may look stronger but is it really... it seems "theory" is the cause of alot of arguments on here in all kinds of threads with no proven data to back it up... just sayin!

so what is the max HP of the indy block? also what is the max HP of the world block . does anyone have any proven data on this (other than looks)

---

Quote:

---

yes I realize that but the point is the holes are smaller than the other block manufacturers.
making the indy block inferior in one of the most important areas of a block..oiling.

and I was wondering if anybody else was drilling them to match the bigger holes the other manufacturers have so I wouldnt have to add more external lines
I believe the holes are smaller even than the factory block

I would rather use top end restricter, return lines or a accusump system then flood the rotating assembly with return oil.Our own Indy aluminium blocks have literally 4 to 6 seasons on them and 100s of passes,the last count my 588" had 686 passes and Don's 605" was approaching over 500 passes.Pap Ross,Chaz and other have the same reliability. Go figure

On the wide pan rail Indy block. Is indy the only ones that make a pan for it? (Dragster style)
Bob, your making me lean toward a 605 instead of a 572 for our Dragster. No power adders.

As far as I'am concerned the 572" is an orphan,it does not show any gain from a 540".If your going to build for big cubic inch power than 600+" would be my choise and that's still small for todays standards.Charlies' Pans and others build the wide pans.Even with the standard pan rail we have solved the oil return and pressure problems with the afore mentioned,restricters,external lines or accusumps.

so you have an alum indy maxx water block
and you have safely drilled the oil returns with no water jacket issues?
that is what I want to do

---

Lets be sure which oil hole that are being referred to:the ones in the lifter valley or the ones at the lower corners of the heads.The ones in the heads have a offset to align up causing a slight restriction.make sure that these hole are free from any silicone and gasket interference.

Quote:

---

it is the oil return holes in block at the four corners of deck surface
you are correct they are offset from the head holes about half the hole and much smaller than the head holes
from looking at world and kieth black they have corrected this but not indy
wondering if I could drill them bigger without causing water jacket problems

---

That's what I thought,we usually make sure they are clear,put .050 restricters to the rockers and install a 3 quart Accusump.If the issue presist we drill and tap the lower head area about 1/3 the way from the front and back and run two external return lines to the pan on each side of the engine.

it releases the 3 qt. any time the engine oil presure drops

umm, you'll need to tell me how all the 3 quarts is going to be released out of the accusump when released. i've done lots of pressure testing using water, you fill to the top with water then squeeze more water on top till the required pressure is obtained. when you release the pressure, only the extra water that was required to reach the pressure escapes which in say 3 quarts might be 1/2 a quart extra to make 80 psi. now i know we're referring to oil here but the characteristics will be the same. you will not get the 3 quart capacity of the accusump escaping into the pressurised oil system unless there's something else to displace the oil in the accusump, you'll be lucky to get 1/2 a quart at the most, depending on the system pressure. if the accusump was pressurised by a gas then you'll get more oil out of the accusump but since from what i can understand, you pressurise an accusump with oil pressure by giving the engine some rpm & then closing the valve. maybe i need to clean my glasses but i'm not seeing it. all i can see is a brief period of extra pressure but not an extra 3 quarts majicly entering the oil system.

THE ACCUSUMP IS PRESURIZED WITH AIR BEHIND THE CYLINDER. IT PUSHES OUT THE OIL

I have seen wide pans the fit regular blocks. the bolts were installed thru tubes welded into the pan

Is oil return a problem with B1 heads?

---

We have limited experience with the B-1s,but we found that getting proper oil to the rockers was a pia and yes we installed external oil drainback lines on the B-1s.If we didn't then the amont of oil at the valve spring seats was a large volume until it got high enough to drain to the lifter valley.

Ken,
Does the Indy max block require a special oil pan? That gasket doesn't fit both blocks, so it looks like the oil pan would need to be special too. ???

---

you can see in the pic. Its wider, no a stock type pan will not work on mine.The pan I have caused the problems with me and INDY.. not gonna go into it.. as said from Fred it does have tubes on one side to install the bolts.. gonna toss this out .. Anyone seen the main webbing pulled out on a indy max block. I know someone that used alot of Nitrous and it happened to one of his blocks. these where early production blocks.. don't get in here that much anymore.. Hope everyone is doing Good
