full race 383 build.
I have a fellow race who is looking to race a new class next year. Car is a h body that weighs 2820 with him in it. he currently has a vortec headed 355 don't know much about it as it was a online rebuild engine, car went high 11's on a 125 shot of N20. He wants to go 10 flat N/A and save the spray just in case. I said since his block needs bored he might as well go 383CI and run 110ll since he has been running 91 oct as that is all we have up here at the pump, he does use some kinda octane booster currently not sure what.
My thoughts on the 383 would be 550hp N/A, I was thinking 1k200 or afr 195's with 12:1 comp and a solid roller cam. how far off am I in thinking on this combo?
