Piston weight ?
RPM ? Stroke length ? Steel or aluminum rod ? ! ! With 720 gram bare piston, I run .036" , to 7400... no issue. |

We ran .050 on a 68 Camaro Z/28 stocker back in the early 80s. Those were the stock piston rule days. We wouldnt have if we could have cut the valve reliefs

Since this is obviously not a Stocker engine, why not cut deeper eyebrows for piece of mind?
