just picked up some rods with pistons and trying to figure out what pistons they are. There is a number on the top of the piston, 6541M815. I tried searching the number to see what it brought up and did not bring up anything. I know they are low comp pistons out of an LS. I am not going to use them since I am doing an all motor build but what to know what they are so I can sell them. Thanks for any help.

 

u need to show a pic

 

Wiseco has a K541M815 piston.

81.5mm with a -12 dome (~8.6-8.9CR depending on many factors).

Same pistons I have in my build.
