Skippy50 Posted January 11, 2023 Share Posted January 11, 2023 Are these pistons standard or oversize? Are they still available? Thanks Link to comment Share on other sites More sharing options...
oldsteel Posted January 12, 2023 Author Share Posted January 12, 2023 I would say standard bore. My picture shows a 3 1/8th dia. If you go 10,20,30 over that would be made up with the rings. Please check your Old Pistons dia. I’m not an engine builder but the rings take up the over bore. Yes I have them 100.00 +shipping Thanks Tom Link to comment Share on other sites More sharing options...
Skippy50 Posted January 12, 2023 Share Posted January 12, 2023 Would it be possible to PM me with a phone number. The pistons are for my brother and he doesn't have a computer. I'm a new member so I'm not able to PM any members yet. Thanks, Geoff Link to comment Share on other sites More sharing options...

Bloo Posted January 12, 2023 Share Posted January 12, 2023 The pistons have to be the correct size for the bore. Today a .030 overbore gets a .030 over piston. The piston box in the original post says "semi" on the label. These might(?) be semi-finished pistons, in other words not ground to final size. A micrometer would tell the story. In the old days, sometimes the pistons were final ground to size after the bore size was known. Link to comment Share on other sites More sharing options...
Skippy50 Posted January 12, 2023 Share Posted January 12, 2023 Pistons need to have a specific amount of clearance, usually only about .0015 -.003 depending on application, regardless of bore size. Rings are not meant to take up the difference. The pistons are marked SEMI so they should be oversized and then machined to the proper size. They would need to be measured with some calipers or micrometer for an accurate size. 2 1 Link to comment Share on other sites More sharing options...

What Skippy and bloo said, there is more to over bore than just rings on standard pistons. Link to comment Share on other sites More sharing options...
