I have a couple of 702 v12,s that the piston is stamped cam 3032. What does that mean?

It might just be a part number. See this Yamaha

Usually the oversize markings are like this "0.30" under or over the part number.

the piston is stamped .020 and then it is stamped cam 0332, I posted 3032 that was wrong . I understand the .020, but can not figure out cam 0332. I will call a machine shop that worked on these back in the day. Bob
