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

You use a r5 cam and have the snout modified by lsm.

Update, it is on the run stand waiting on the right length pushrods and a few fittings and I hope to have it running.
Will keep you posted.
Thanks
Mike

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

Update, it runs, no bad noises, cold oil pressure is 70-90 psi depending on RPM, hot(170F) oil pressure at idle (1150)is 40-45psi. oil pressure goes to 90+ when you bump the throttle. I did run it at 2500 to 3000 for 2 to 3 minutes to make sure the oil was gettingg back to the oil pan. So far the oil is nice and clean no water in the oil. The only thing I am concerned about is the amount of oil going to the top end, not much getting there. There is a leak on the front of the lifter valley cover I think that it's the set screws for the oil passages to the opposite side lifter galley, crank case vacuum is good. I took a video but it sucks so I am not going to post it. I plan on running it and working out some small problems and then go to the dyno.

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)

I have it running on a run stand, as far as the quality of the aluminum it is good there are a few spots that I can think of, one is in the core plug in the lifter valley. I had to tap them out to a larger size 1/2 NPT. We didn't find any porosity when we bored the block out to put the sleeves in and nothing when we decked the block. Yes I think the block is designed for a dry sump oil system.

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
