I am going to have to replace some pistons. I am waiting on the machine shop to tell me is I have to bore the block. My question is how can a see the stock information on my GM pistons stamped #14097021? I am trying to make sure to get the right dome so that both motors are equal.

Thanks for the help in advance.

what size engine,what hp,and what year?

from experience,if you popped one engine then the other is not far behind doing the same thing..your best bet is to get them both redone,to me replacing pistons is like replacing spark plugs,do all or do none...

just my o2

Unless the other motor is fairly fresh, I'm with mrfixxall
