383 build
Right now I have some TSP stage 1 LS6 heads milled to 59cc and i'm running a 228/232 cam. If I wanted to build a 383 from the ground up, how can I go about keeping the same compression (11.5:1) and running a bigger cam. If I buy pistons with valve reliefs to allow for more PTV clearance than don't I lose compression? I was thinking something along the lines of a MS4 if not a little bigger.
