I have been looking at low compression pistons for a 351w project I want to start. When I look at the CR for the pistons its also dependent on the size of the CC of the head. For example: 9.06CR for a 63CC head.
My question is does the CR go up or down dependig on the size of the chamber? What else determines the CR going up or down?
