ok, T-Man performance 95" kit. stage 1 heads, and he cut my jugs. i used Zippers Performance, Red Shift Cams, the .577 gear drives, the S&S gear drive kit. (i will never use chain drive again) so, those cams recommended the compression be 9.25-10.25. so, i had him cut the pistons to 9.5:1. SMOOTH!!!!!!! WOW!!!!! power is good, about 100 hp and 100 tq. nothing to brag about, but it does move out smartly. butt, it is the smoothest motor that i have ever operated.
