Pistons

[c.o.]

Can any of you engine guys tell me what these markings mean? In the past on various rebuilds I have noted a stamp to indicate the size but have not found anything on these pistons. Could the 1 mean it's 0.10 over? Thanks in advance for any thoughts.

Cory, it's been my past experience that the size is stamped on the crown. If there's nothing stamped then they are probably standard. You can always mic them to be 100%.

It had me wondering Dewey! There was no stamp on the crown and I thought possibly the cast numbers meant something on the skirt. I guess I've never started out with a standard size... Thanks!!!
