We bought an engine from a local drag racer, he was going to build a big bore motor and gave us all these extra parts. with it was a set of pistons, he received from rick kermil mac dizzy. big bore pistons, I am not sure the size but took loots of pics and can answer any questions you have. they are pistons rings circlips wristpins. I have one sleeve but couldnt find the other.
