more xr1 problems - 04/29/13 12:29 AM
just want to put the word out on the xr1 blocks they are junk and kent dose not stand by his product I will spare you guys all the drama but I would strongly stay away from this block . this is to bad because as a mopar guy I know there is not a lot of cool after market parts out there for us. this is really sad that kent will not fix his mistakes it is every body's fault but his. there are others out there that wont say any thing yet because they are trying to get there money back from kent.. he is a millionaire and told me he cant pay me back 180$$ that I paid to ship the first junk block back that could not be fix.

Re: more xr1 problems - 04/29/13 01:28 AM
thrust main is wrong.. head blot holes are off.. oil pump on the rear main cap has some problems. the lifters are not all in the wright place. some problem with the oil galleys. but nothing that cant be fixed for 2000 bucks more stay away run
lets just say every thing that is done by kent has to be redone. on this block . but I bought a set of w8 heads from him that were great so this problem seem to be only with the blocks

Its things such as this that make the term MADE IN AMERICA meaningless. I wish Dart would make Mopar blocks, maybe then we'd have something to work with instead of work on.

I was on the fence about going this route.... I'm oh so glad I went the 9.200 R3 route so far. Mine sonic checked well and the build is under way. It really sucks that people are having issues with these blocks. The small block Mopar community could have used a choice.

With the availability and the HP numbers coming out of the Gen 3 I don't see this happening either. Why waste time and money on an antiquated engine?

With all this bashing and negativety about a product I'd thought I would post a possitive report. A customer in Texas has an XR1 block, W-7 heads by Visner with turbocahrging. 1300 at the rear wheels. The math works out to something like 1500+ at the crank. Pretty good amount of power handled by a block everyone seems to like to throw under the bus. The point being these are good blocks.

Sounds nice and all but his ISN`T correct and apparently the owner isn`t making it right..................That`s what makes a company good............standing behind your product and if things aren`t correct you fix it or send out another and not be a greedy [Edited by Moparts - Family Friendly Site - Keep it clean].

NO i have spent more than 2000$ EXTRA no a block that was sold to me as only hone.and put it together 
.that is great news about some one in texas. these block have been sold for 3 years and one that runs sad story. hope he can pull it together a fix these problems it could be a neat dill. please don't try to down play all the problems with these blocks .

Ok... the drift I got so far is that this block will
take a W series head... is it a 59* or 48* block
and whats the standard deck height... is it a 4 bolt
main, whats the cam tunnel bearing size... sorry

hey mr p yes it is a r type block and has some cool stuff going on but all the bugs on kent side have not been work out yet . the second block is alote better than first. but like i said in my earlier post still a ton of problems. I did not want this to be a kent bash just telling my story

. This is the block with the head studs in the wrong location and had to be moved. Blocked leaked water into 3 cylinders all weekend long. Engine is apart now to try and repair the problem. Not sure who's fault it is but no for a fact it was the block.

So because he half accomplished a difficult task it's okay to pass the buck to the consumer? I don't follow and am no longer considering an xr for my build. At 23 I'm not rich so good money on bad parts isn't my motto.

I'm sure bringing a block like this to market is difficult and expensive. I'm sure anyone that bought one was expecting to do some minor machine work to it but having to redo major machining probably wasn't in anyones mind when they were sold a block with requiring only final bore and hone.
Most of us guys don't have unlimited funds to drop on an expensive part and then spend nearly as much in machine work to make it right. I applaud Kent for doing it but it seems in my opinion, and only my opinion that the execution could have been a bit better. I'm not slamming him in anyway and I don't own one of his blocks but I did consider it. If he ever gets them straightened out I may consider one in the future but quite frankly for that kind of coin a gen3 hemi seems like a better deal.

MR JG309 this is a joke 2 1/2 years and your motor don't run yet what a great guy kent is 
if he is so good why isn't your motor running... o buy the way I did not see the word mopar or dodge on my block.. and a set of w8 wont bolt up to it because the bolt holes are in the wrong spot maybe I should try some brand x heads it is your duty as a mopar guy to put the word out and save some others from all this BS

I also know the gentleman that has the XR1/W7 combo and they were up all night trying to fix it before a race. I can promise you that the 1300hp he made with it was way down! He was using a F1X and it should have been a lot higher.

Antiquated???
Let's see a 420ci Gen 3 ring up 1000+ N/A. An "antiquated" carbed W8 will get there all day and a SERIOUS 2x4 drysump deal will all the bells.......forget it. A Gen 3 would need an adder to make it appear to be a race.
What should be being produced is a good block in multiple deck heights and new raw 8s so CFE can carve away.

Re: more xr1 problems - 04/29/13 11:58 PM
hey everyone. my (block porn)post turned out to be a dud. i'm not here bashing as mentioned earlier. just making everyone aware. my block turned out to have over machined lifter bore's. this surfaced after fireing it up & didn't have oil to 5,6,7,&8 rockers. my receipt said bore's were sized & honed. didn't really check, my stupidity. pulled & stripped block bare. told kent i'm done with his block & want a full refund. he agreed. here are some other issue's i had, again, just thing's that should not have to be corrected by me. thrust .004 too wide on the block. bolt holes don't line up the heads. oil pump drive casting dosen't fit in the #5 bearing cap. bottom 2 holes for the timing cover need drilled deeper & retapped(only 4 threads). don't know if this would be a problem, my block started out 9.600 & was decked to 9.200(for the setup i'm currently running.) that's 400 thou cut off the deck. that's alot. i had to drill & retap all the head studs cos there was only 1/2 " of thread left in the deck. seems like alot of crap to deal with for the money. i give up. 4 1/2 months of dickin around. i have a r3 block on the way. all will be good. i'm not bsahing, cryin(like some may think), just stating facts. kent is a great guy. i give him credit for steppin up to the plate. his block is a stout peice. too bad he dropped the ball on machining part of the deal. thanks for ur time. stay safe, seeya.

I feel bad for your leg and I hope you get your healing soon.. and your r3 w9 366 making all that hp is cool.. but that has nothing to do with these blocks that kent has sold as been one thing and they turn out to be something eles so he is a liar and a cheat in my book

Re: more xr1 problems - 04/30/13 01:01 AM
Here it is !!!!! The block stinks. I think the siamese r block will handle anything WE throw at it,and there available at any dealer.I was gonna buy the aluminum version and the builder said 2yrs ago there a nightmare to machine and stop leaks on.

Re: more xr1 problems - 04/30/13 02:26 AM
Guys, there's only 2 words that someone bringing a product to market that is as complicated as a new block should use to the fullest. Those 2 words are: QUALITY CONTROL!!!! Every one of the problems discussed in all the posts about XR1 and XR2 could have been found and corrected with a viable QC program. It tickles me when some try to justify his problems by saying how complicated it is. Guys look around that's a piddling little machining problem.

I've had problems with just about every aftermarket block I've used. Not justifying just saying.
We had more quality control in a greasy 50+ year old steel mill then this. If i put out work like that rebuilding a gear case I would be on the street in about 5 minutes. Its a NEW block in a machine shop guys. Take some pride in your work and get it right.

Re: more xr1 problems - 04/30/13 10:50 PM
I can't speak about everyone's XR1 issues but I do know some things about the XR1/W7 engine. That block was initially purchased from Kent with no head studs and lifter bores machined in it. Reason being, it was originally going to be used with P5 heads. Later on they decided to run the W7's to go heads-up class racing. (Mainly X275 and NMCA Xtreme Street and Street Outlaw classes.) The block was then sent out to be machined for head studs and lifter bores. In the process of drilling the head studs, they were drilled in the wrong location and they had to be plugged and re-drilled again. Water was basically coming up through the head studs and leaking while on the dyno. Being a former manufacturer rep I can sympathize when certain details are left unknown and I just wanted to set the record straight on this particular situation. Thanks!

If only Maskin(DART) would release Mopar blocks all the problems would be solved..

Why not just use the proven/bulletproof R5 block? An engine in the 420-430 CI range can be built easily.
I'm going to look at a complete R5/P7 next week, and that will be my plan if I end up getting it.

Initially that was the route I was going to take. I even ordered a crank from Winberg to go up to 400 cubes. After waiting 6 months for a one-off crank and with no firm deadline on when it would be done, I decided to take my money and go with the XR2 option instead. I feel like the XR2/P7 engine combo can be a viable answer to the small block guys who are craving more hp. Take a look at all the SB2 high horsepower combinations... no big secret that the heads are the key. I have had conversations with a few different well known head porters and they all agree the P7's have more potential than the SB2's. Unfortunately for us small block Mopar guys, there is no known proven recipe to use these heads in a 400+ cu.in. engine.

The exhaust guide could be offset a bit to get a bigger intake valve in to give it some air, the cam would be a matter of trying a few. I think a R5/P7 in the NMCA N/A 10.5 class would be a real competitive combo in a good car.

The sb2.2 actually fits on a chebby stock block.If they(mopar) got the bugs out of the blocks or even made one that could go 4" stroke,I would guarantee you'd see even tons of mustangs w a p7's motors in em.One of the best sb2 builders in the country said that p7 could do the same if not more then a sb2 head.

In the past few weeks I contacted LSM about making a billet Alum block. They will make it to spec and the cost is the same or less than what I have in the block I have now and comes ready to use. Here is the draw back. You have to order 10 blocks on your first order and my pockets are not that deep. If 9 other guys are willing to step up then lets place an order.

Yes this would be your best bet. I know they are still out there. I got one still in the crate. I keep it just in case of an emergency. Also have a spare Aluminum R4 sitting in the floor!

If you want an aluminum block, Ernie Elliott makes those. Deck height starts at 9.320" IIRC.

I understand some of you have issues with these blocks. But did we forget that R3 blocks have had several issues as well. Im happy to see someone making an effort to make something for the small block mopar community. Were lucky that some one is even making them with such a limited market.

I agree,if we can just get a few more HUGE dud's.That should improve an already dying mopar base.No offense but what did you actually read in the last 2 pages? Lol

I may be wrong but I think the Elliot block is a
cast block. The LSM block starts out as a block of aluminum and is fully cut to spec on a CNC. You
have the benefits of making the same power as a cast iron block but without the weight. Also your not limited to a short deck height. Just something to think about.

....but it sounds soooo easy! (quote from the block description)
"This block is not assembly ready. It will require finish bore & hone, possible line hone and final deck height cut, and possibly oil holes to the cam bearings depending on cam bearing type chosen. "

Ok... the drift I got so far is that this block will
take a W series head... is it a 59* or 48* block
and whats the standard deck height... is it a 4 bolt

to ask all the questions with you having your problems
with it
....a little insight Mr. P.

this site has changed from when I bout my block u can count on 1000 to 2000$ more to fix all the machine work. and don't for get I got one block that could not be fix. I had to pay to ship it to kent because he did not have any money.he lied again and said he would send me a new block right away .it took me calling him every week for 5 months be for I got the new block.

Re: more xr1 problems - 05/04/13 02:29 PM
The issue is that the block is NOT dedicated to 1 type wedge head or p style.This interchangeable heads and oiling system is quit a task.,.maybe to much.I bet a million bucks if it was dedicated to just P series head or a WEDGE type there would be very little wrong w it.

I would agree with you to a point but the problems that most of use are having is the basic machine work. like thrust, head bolt holes, lifter size and location.. and some other small stuff

Re: more xr1 problems - 05/04/13 08:25 PM
i guss i should just keep quite because my block is a xr2 & not a xr1,but i do know my machinest told me that almosy all brand-x blocks & dart included have most of the same problims my ritter block had,when ryan put my lifter bushings in he would not start untill i sent him my cam,lifters, cam bearings, he said allmost every engines lifter bores are off, so you need a jig to aleign them corectly,not just kents,only real problim i had was with the maching work that was done before i got mine,kent madeit all good, & i ask ryan if it was fixed right & he said everything was ok,my xr2 block is for the p7 heads only,the wedge heads & cam will not fit, iwas toold when i bought my xr2 that it would have to be bored,alined honed,bussings installed if i wanted keyway lifters, as well as the deck cut to my spects, so i think i got what i payed for,nothing special

Re: more xr1 problems - 05/04/13 08:43 PM
everything you mentioned gets done on any new aftermarket block.MOPAR cast arent perfect..but its minor stuff and any good builder would do before an assembly anyway ie check clearences etc etc.

Re: more xr1 problems - 05/04/13 08:47 PM
why doesn't someone who goes through the trouble to design and build a block like this make sure the machine work is correct before selling them?wouldn't it be nice to have someone you can trust?

Re: more xr1 problems - 05/05/13 02:28 AM
I for 1 would like to personally thank Kent Ritter for the endeavor he has intered. i think its kinda ironic that any time someone needs some small blocks parts usually you end up getting them from him. Yes the blocks have some issues. I personally have an XR2 block. When i bought it i was told that i would need to size the mains and the cam tunnel. I chose the keyway lifter route so i had that machine work also. I also had to cross drill the oil passage to the lifter bores, just like a 48 degree R blocks that nobody has ever had a problem with. Iam sorry for those that have had so much trouble, and I hope he makes it right with you. Not saying Kent is perfect but he seems too be the only person to try and help the small block community out. We could start a list of all the R block problems, indy head problems, jesel belt drive problems and find out how much assistance those companies have helped you and then we could just all go big block then everything would be easy. Good luck to all involved I just wouldn't hate on kent too much because he may your only choice for parts in the future.

I know that I worked hours upon hours of overtime at my job to build a motor. All to get screwed over by Indy. It is very frustrating. Some things are excusable, some are not. I can understand if some basic machining needs done but this is ridiculous and problems should have been addressed before those blocks hit the market. I am sorry for all that are cursed with one.

Re: more xr1 problems - 05/07/13 04:24 PM
thats ok i like mine,its great only 1 problim that was not told to me when i bought it, & kent didnt even know it till ryan found it,but kent fixed it, i've got both a rittr block & a r3, had as much trouble with the r3 as a ritter block, i live in the st.louis area & finding a MOPAR machnest is like pulling hens teeth, finisly found a guy that can do the lifter bushings, but nether one is a bead of roses to put together, so when you get your block measure every thing on it, my r3 the lifter holes were off amoung other things, so make sure you check everything like i said earlyer

Re: more xr1 problems - 05/07/13 09:02 PM
I could never understand this brand specific machinist thing. If a shop that builds mostly GM stuff can't do basic machining on my engine just because it is a Mopar, I sure as he## wouldn't want him to do machining of any kind for me. It's not rocket science. Things that are round need to be round, things that are flat need to be flat and if they need to be parallel and equidistant to something ie the crankshaft, make them that way. That stuff is all Machine Shop 101.
Cylinder head porting? Now that is rocket science.
I think the cause of a lot of these machining fiasco's is that everyone thinks that CNC is the be all and end all which is BS. Set up a CNC machine wrong or give it the wrong information and it will machine junk all day long. I would bet that is why this XR block has head bolt holes in the wrong place amongst other deficiencies. Just because it's a Rottler CNC doesn't change Machine Shop 101.

1000%.... if you have bad data on a CNC
or a bad zero point then you get alot of trash... but
certain builders.. as in a mopar shop tend to know
more about cam choices which mopars tend to need
something different than a GM or ford... but the basic
machine work is just that... basic... like said... 101

Re: more xr1 problems - 05/07/13 10:37 PM
Brand specific shops will give you a better job. Go to a machine shop that doesn't have torque plates for a mopar. What do you think happens on the hone? Try jigging a block for lifterbushings without the brand specific tooling. It can be done, but not with the simplicity and accuracy of brand(or block) specific tooling. Bottom line, the work you pay for will be better at a shop that specializes in your engine. You pay for set up time. You also get the advantage of a trained eye to "brand specific" traits and faults. Any machinist can make a round hole at the machine shop. Will it be straight after assembly???

the first block I got from kent the lifter holes were off by 1/4in and the oil galley in the cam tunnel broke through . it came with epoxy in two other oil passages 
tell how will you fix these little problems

You know when you stated above that you have a mechanical Engineering degree I went and checked out your bio as I worked for several over the years as a Millwright. Then I see village idiot listed by you in your own bio. Just wondering if you HELPED any in the designing of this block.

Well I for one will be waiting with baited breath on this one as Ive been disappointed seeing the issues others have had with them.
The last thing I wanna do is be stuck with a 5K block on the other side of the pond that needs another 3K of machining to make it right.
In case Kent doesn't know it (Im sure he prob does though), there are gearheads interested in this engine that don't live Stateside but are die hard SBM guys that ware watching and waiting......

Why not just use the proven/bulletproof R5 block? An engine in the 420-430 CI range can be built easily.
I'm going to look at a complete R5/P7 next week, and that will be my plan if I end up getting it.
Initially that was the route I was going to take. I even ordered a crank from Winberg to go up to 400 cubes. After waiting 6 months for a one-off crank and with no firm deadline on when it would be done, I decided to take my money and go with the XR2 option instead. I feel like the XR2/P7 engine combo can be a viable answer to the small block guys who are craving more hp. Take a look at all the SB2 high horsepower combinations... no big secret that the heads are the key. I have had conversations with a few different well known head porters and they all agree the P7's have more potential than the SB2's. Unfortunately for us small block Mopar guys, there is no known proven recipe to use these heads in a 400+ cu.in. engine.
King Crankshafts are ~ 8 weeks lead time, I have a billet crank on order with them now.
Ernie Elliott has built over 400 CI P7's using his aluminum block, he did a 440 CI, 12.2-1 compression/mild cam streetable version that made 940 HP through a cast intake/4150 carb, a dual carbed version made 1015 hp. The block doesn't have the typical HP loss associated with aluminum blocks, he developed a improved sleeve system that showed an improvement of 12 HP.
Anyone with any questions regarding these blocks or associated parts can PM me for more info.

Re: more xr1 problems - 05/11/13 03:23 AM
Dave when I last checked they were $7,500. This is machined and ready to bolt parts in. The lifter bores are bushed for Jesel Keyways so that is a little more money but the cylinders are finish honed, the deck is square and the line bore is dead on. I think it is a good price for an aluminum block I just have not pulled the trigger yet. Still playing with Bob's ole junk.LOL

well guys I was really hoping that I would have some good news about this block buy now. BUT I went to put the oil pump on and found out that it will not just bolt up. the part of the cap that receives the oil pump drive is under size. not a big dill right. sow got this fixed. the quick fix took 5 to 10min on a mill. finaily get the pump on the cap and found out that when kent drilled the oil passage threw the main cap he just eyebald it. the hole is drill so far off the oil pump did not intersect. well back to the mill for an hour or two. now this is turning in to BS. get that fixed. then the guy that is doing all this great work for me says he don't no if the pump will seal to the cap because the orginal hole was drilled so close the the edge of the cap he did not trust it. sow off to the welding shop. one other small problem is kent stamped numbers in the cap right were the oil pump need to seal
guess I will have to get the cap resurface
this is not a bash just telling you guys what it took to get an oil pump on my xri block

Most stock gasket sets have a paper gasket for the oil pump. I machined the surfaces to not need the gasket. Or was using a soft aluminum spacer on my stroker so it did the sealing.
