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.

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. 1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.42@138.27 Livin and lovin life one day at a time

I think if kent put one of his motors together him self he would see what all of us are going through. and he would find a better machine shop..

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!

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.
