what compression

[CstMCgR]

What compression piston would be best for a 416 build with stage 1 cam?? It does nothing but run trails with all my buddies.

I would get a JE Superlight 12:1 piston. You'll have plenty of torque, and still maintain high rev speed due to its low weight. 13:1 will be too heavy.
