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

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. Kevin

 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

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???

so now kent is going to build a motor  .. Now he told me that there are a hole bunch of them running all ready  guess not.  as for the build I hope this is to really iron out some of these major problems. not just some smoke and mirrors. used to take advantage of more mopar folk

I am doing the build. I am doing this to show that all is not gloom and doom with these blocks. They are out there running now. Some pretty nasty dirt cars are using them.
any links or names of these teams using these blocks? Loved it when Steve Francis ran mopar for awhile

if you don't mind, who are you, do you have a machine shop etc?

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......

I have been to the foundries and machine shops but I had no input into its design. I have too many oars in water as is. I have several engineer jokes. I like most of them. The Village Idiot thing is one way I stay grounded. A good sense of humor and well heeled humilty are a must for me.

I have 30+ years racing/building/crewing Stock Eliminator, Super Stock, and Comp. cars. These cars have won numerous class trophies and have quite a few national ET/MPH records in NHRA/IHRA. I presently still race in Stock. I have a degree in Mechanical Engineering with a major in internal combustion. I spec all my engines myself then have one of several very good shops do the machine work. I have a full service shop where I restore muscle cars. I would like to have a machine shop too but you can't do it all. One azz ache business is enough.
thanks, I understand and wait to see your build. I hope it is objective and accurate.
