Again a 355 with Dished Pistons and 76cc Heads has More then 8.2 C/R . How about if the Block was Decked ? And Like always when heads are Rebuilt -0.10-0.20 True-ing up cut ? 0.15 Head Gaskets . Now your near 9.1 C/R . Like I said I know of a Camshaft that works real well in the 8.5.1-9.1 C/R SB Chevy builds . Tech Were are you Coming up with your C/R #s ?? I ran many different Heads / Pistons / Gaskets / I can Tell you in Real World SB Chevy Builds what Octane Gas you Need to use . Don't Let that Math make you run 92 Octane Fuel when you do not want to . As for the L79 cam GM#151 Back when we did not have all the Camshafts Like Today . I ran that and the L-82 Camshaft in 9.1 C/R 350s with it advanced 4-degs . The cars Raged and ran real good on 89 Octane Fuel . Yes Today there are Better Camshafts and I do think it is best to CC your heads and Piston dishes . This way you will Really now what your C/R is .
