[QUOTE="swirk, post: 13058585, member: 69338"] I am running flat top pistons (told this was 10.5:1 by Manley) and a Procharger P1SC. Highest boost during tuning was 12psi (I have an overdrive crank pulley). Tuner recommended an octane booster (torco) which gets added during every fill up to avoid detonation. Torco adds +11 to the octane rating. Forged lower end. Teksid block. 505 whp @ 5700rpms on a conservative tune. Not sure if you can run this combo on straight pump gas. I was told by the tuner that the flat top pistons were limiting me. [/QUOTE]
