355 chevy hp estimate
I just registered today and my first question is concerning my motor. I would like to hear estimated hp from various sources. I have a 355 chevy with S/R torquer heads (76cc) slightly ported and polished with 8.6:1 CR (catalog ref of piston p/n says with 76cc and .040 head gasket equals 8.6:1), Victor Jr. intake, Holley 750 vacuum secondaries, .490 lift both sides camshaft, 2.02 intake and 1.60 exhaust valves. The head gasket has been changed to a .015 steel shim gasket. I'm guessing around 360-375 at the crank because this was supposed to be a 400hp motor but I'm thinking that was with the 67cc torquer heads.
