Hi Everyone,

Trying to identify this piston. I was told when I purchased them years ago that they were .030 454 Chevy pistons. After doing some more research, what I have found on the interwebs is that they appear to be 383 Mopar pistons. They measure 4.28" (4.25 +.030) and they have "7023P" stamped on the top and "201-99 B" on the bottom side of the piston. Everything I have been able to find online points to them being 383 Chrysler pistons, which I guess are also 4.25" standard bore. Just wanted to get second opinions and confirm my suspicions. Pretty bummed they are probably not the 454 pistons I need.

Here is a link that led me to believe they are probably Mopar pistons. 383 Dome Piston Help - Moparchat - Home of MOPAR enthusiasts worldwide!

Thanks in advance.
