I have pulled apart my 56' 235 for an overhaul. It was worked over at some time before I got it because the rod bearings are 10 under and the cylinders have very little wear on them. The pistons have 040 on the dome. I'm thinking that means they are 40 over? Also does anyone have the measurement of what the standard piston is?

Thanks.
