PISTONS: Flattop or Dish for stoker....

I have a 360 with iron magnum heads that has 10.6:1 static compression. I have a 224/230 @ 0.050 cam that gives me 180-190 psi of cranking pressure. I run this engine on 89 octane and can get by on 87 if I am careful.

With a cam of 250 degrees duration @ 0.050" I would think you would not have a problem with 11.5:1.
