Help with cam selection

You won't need much of a cam to reach deep 11s in that combo. Personally I feel the static compression is too high. The 4" arm will make the tunnel ram work. No need for higher compression because with iron open chamber heads it leads to detonation and ping problems. I'd rather see a dished piston used and the static left around 9.8:1. With a much smaller cam it will make enough steam to put that car into the 11s. That is if 11s is the goal anyway.
