what compression ratio would be best I want 650 to 700 hp I can put on my 317 and have the 8 to 1 or the 243s and have the 9 to 1 I wanna run pump gas and around 12 to 15 lbs of boost also how much power will I lose na from 9 to 1 to 8 to 1 since I will have to drive the car a little while before I can get my D1 kit

9.5/1 is what I recommend for a centrifical supercharger such as a ProCharger D-1SC. Bob

With a good fuel system and tuning, you can run 16 psi with those heads with head studs and be in the 750 to 800 rwhp range, and not have any problems. This is with a forged bottom end. Bob

I got a forged 370 stock crank diamond pistons,eagle rods, clevite bearings, and I just picked up the arp 12 pnt head stud kit and my ls9 gaskets with ls6 intake, fast rails, and 60 lb injectors. I don't know what fuel setup I'm gonna run yet I was looking at the nasty performance dual in tank setup on a hobbs switch but don't know what that will handle .
