WRIST PIN FIT?

262 cam is pretty small.
You may end up with too much cylinder pressure, depending on your finished true compression ratio.
Because you want to save machining costs, I suggest you wait on ordering a cam until you have that Scr number
I have the cam already. It was recommended by Comp Cams. I ran the numbers through the Wallace dynamic compression calculator and came up with around 8. It looks like the pistons I am considering are flat tops with 7.5 cc valve reliefs. My combustion chambers were cc'd at 69cc's.
