I'm no pro, but with a cam that big(I assume 236*@.050" lift) it should have an intake closing point about 70* ABDC giving a dynamic compression around 8-8.1:1 if I'm not mistaken. I'm figuring its got 4.030" bore, 0.039" gasket?, stock deck?, piston .025" in the hole? to get about 10.5:1CR. It should run ok without detonating if my math is correct? How well it runs in a truck is another story. I sure wouldn't recommend towing anything!
