Im building a 97 npi block and have trick flow heads with cms 2.5 blower cams going on it. my block will be done soon at the shop and im having it bored 30 over. so im wondering if any of you guys could recomend cc's for the piston, this is going to be a boosted motor on about 12psi. and capabilities to go up in psi if i need to. so im thinking 23cc dished pistons will put me around 8.7 cr? any insight?
