Anybody using the R5/P7 for racing?

Older post, but figured I would search before I made a new post... How about oil pan and motor mounts? Will I need a diferrent front end, tubular or can I get a oil pan or does it clear. The crank spacing appears to be not as much an issue today, what other things will I run into if I decide to do this? I have a couple complete ones found for a decent price, and Im very intrigued!!!! Any help? I dont really want to cut up my car though to do it....

My head porter does alot of P7 heads for cup cars and said it's a real efficient engine. 840 HP with a 9.0 CR and a tiny carb I believe it. The main parts are readily available for cheap it's going to be the small, reusable stuff that will cost you though. Theres a guy that sells mopar race stuff on ebay that goes by seatmon. I his last name is eatmon and he gets alot of the parts for the R5/P7 engines I think his brother did a B body with one.
