Thank you guys for all your effort helping me figure this out. Sounds like the compression ratio should be lower then what the seller and calculator was telling me. Sounds promising indeed. I figured the cam was to big for the little 350 but am no expert so wanted to get input from you all. Shouldn't be to hard to sell the comp cam for enough to get the summit cam. I have heard good things about it.

I left out the gasket diameter info on the calculator this made a bigger difference then i expected. Opps. Lesson learned

I seen a pic of the pistons they don't have the black coating on the skirts so I assume they are the cast version. They are flat with dual valve reliefs as i said earlier.

The old TRW L2339F forged pistons did not have the black coating. But the part number and oversize should be stamped on top of each piston, whatever brand they are.
