I bought an engine from a member on here that said it had diamond boost pistons in it. Well I took it to my engine builder and he can't find the part number of the piston in Diamond's catalog to get rings for it. So I don't know if these are Diamond pistons or not. I need some on this help guys
If these aren't Diamond pistons then me and the guy who I bought it from are going to have a serious talk![MAD](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_mad.gif)

The only number I could get off them was 6392fs and they are for a 4.000 bore and 3.622 stroke. Here are some pics of them.

I tried looking on Wiseco's site and the part number I listed doesn't even correspond to any of their part numbers. Diamond's part numbers are 5 digits and this one has letters in it, they don't have any letters in theirs.
I really need to find out what piston this is. I'm going to see if I can talk to the guy i bought it from and see if he has any paperwork or something.
I'm also going to measure the rings and get back with you Frasier

What numbers/letters are on this piston? Also, where are those numbers or letters stamped/cut?

The numbers are in my first post and they are on the piston in the 1st pic at the bottom of the 2 eyebrows on top of the piston.
You can't see them in the pic but they are there.
I appreciate the help Matt. I have bought stuff from you guys before and never have been let down.
I still didn't get a chance to measure the rings Frasier but I will do that as soon as I get a chance, but that looks like it won't be til after Christmas.
