Cam and carb selections

I think that is exactly what I have.
OH! Doing a total rebuild are we? Or just a parts clean up and reuse? I just thought it was adding parts to a good running mill.

Did those pistons come out of the block easy? They could have broke when you took them out. Passing over a ridge can cause that damage.
