Two stupid questions.....What is the difference between the XR1 and the XR2 aluminum blocks?
And what heads are you guys typically running on these?
XR2=P7 heads XR1=W7,8,9 heads

XR1 takes the wedge style LA series head
XR2 takes the Dodge P7 head. These blocks were designed primarily to run the P7 heads (As Kent as a very large stock pile of them)

Short block is assembled, At this point in time we are flowing the heads through the intake and throttle body, and with the headers. When that is done everything is ready to finish the long block. The next step is to run it on the test stand. Have a few small things to finish on the run stand. I will post the results and a video of start up and it running. Thanks for all of the input and interest. Mike

So what's a guy use for a cam in an XR2 P7? You use a r5 cam and have the snout modified by lsm.

Wow can't wait for results! You plan on dynoing it or just put in car when it comes off run stand?

Glad to hear that it is running! Is it in the car or on a run stand?

Is this block designed more for a dry sump than a wet sump being that you had to come up with drain backs... and as asked already... how is the quality of the alum and porosity(if any)

Did you use a grooved lifter or bushin, so the oil could pass by 100% of the time. Because the oil galley is dead center of the lifter a groove someplace is necessary.. I used a grooved bushing. So that oil will pass by continuously
