Piston part #
I am going to rebuild my 454's. I have gen 4 blocks which are to be bored .030. The heads are Vortec L29 with stock chambers. I have yet to cc the chambers for volume but I was told they where 105cc. I am going with hyperutectic and would like CR around 9/1 to 9.25/1 Any help with part # would be great. Andy... P.S. even better if anyone has two sets for sale!
