Unless I misunderstood Billy he was inquiring about the volume displaced by his + .080 283 Chevy pistons that protrude .040. The amount they are positive (or negative for that matter) will effect his compression ratio and I think that is his concern. Stock type 283 flat top pistons will have 4 valve reliefs that are approximately 1 CC each, hence 8-4=4 CC.
