11:1 too high for pump gas?

I don't have a bit of trouble with my aluminum headed 10.8 small block 360 in my cuda.

This is exactly where I’m at. Runs well on 93. The cam is sizeable for the street. Bleeding off low rpm and drive speed compression. Paying attention to the engine timing is a key factor.

My 440 is 11.8-1 edlebrock heads and run 94 in it. Never have I herd a ping. Street and strip car.

What are the size cams you guys are running? And, if you don’t mind, the gears, tire size and converter stall speeds.
