NASCAR P7 motors have huge flowing heads and are made to turn big rpm, and have thin rings.
Gotta think they wouldn't be the way to go with a turbo

What ever happened to the guy above with the red avenger? He always had fast stuff and used to post all over. ??

He is going to need new pistons for a turbo motor and at that time he can run any ring package he wants

Been running a 40 pill in my R5 aluminum block. Cylinders have not moved.

Noah Strickland sprayed a 32 pill on his 358 drowning it with fuel and way overtimed. Only damage was pistons. Head gaskets didn't leak.

The biggest problem is finding a cam core to run a turbo grind. Lsm is willing to build one but is pricey. Comp cams said there price was $3000.00 for 1 cam core are $3000.00 for 3 cores. Then I find ought that lsm makes comps custom cores. There are no cores that can go anything over 112 lobe separation. James at Bullitt cams said he is willing to do a custom core, you might talk to him if you are thinking of going this route. If you find anything different I would like to know. Iam talking about roller cams. Good luck.

Leon what have you run on the 40 pill?? That's cool!
