Piston part number help!
I am building a .030 over BB Chev with 4.25 stroke and 6.385 rods or 489cu/in. The problem I have is I'm using the Vortec L29 heads with combustion chamber of 100cc. I would like my compression ratio to be no more than 9.25/1. Has anyone access to any piston mfg and part numbers to help me out? I have not done a cc measure of the chambers but 100cc is what I was told. Thanx... Andy... P.S. This is a dual engine setup on an older 1984 Formula 302 any thoughts on cam selection?
