ok ive got some dome pistons and some almost flat top pistons for my 350. with the domes the motor would have around a 10.5 :1 CR with the others it would be a little over stock i think a 9.2:1. this motor is gonna be in a bracket car. it has ported 193 heads with the stock 1.94 valves and probaly roller rockers. the bottom end will be stock and this is going to be mated up to a 3 speed. ive been told the 10.5:1 CR isnt real streetable which could be an issue for me. if i use the flat tops and buy a good cam accordingly what kind of power can i expect as compared to the domes?
