3.0/181 v6 flat tops. .094 in the hole. It calculated out at 9.75 or something.What pistons do you have?
Buick 350s have circular open chambers. Plus with the small cc heads building it the sbc way at zero deck with .040 quench (head gasket thickness) and flat tops it would be over 12:1. Its a necessity to have a short piston on a sbb. The aluminum heads however have a more conventional heart shaped chamber, but still small at 55cc..094 in the hole?? Way out of good quench range. 162 RWHP. Hope I'm wrong!!!
