318 block and I don't know

Welcome to Fabo Wayne. My first question would be, do those pistons have a part #? Might tell us if they are even compatible with a 318 bore and a 3.58 stroke. I agree with @TT5.9mag that you need some help finding out just what you have. I do believe you got some good parts, we just have figure out what will work with what?

My gut tells me you may be looking for a 360 block to build. We'll see?
