Piston Set Question
if you go HERE you will see at the top a piston Set A (std) and a Set B (std) and of course the .25 OS Set.
my question is, what is the difference between A and B? I'm looking to do a small rebuild and just give my engine a refresh. Nothing to crazy....yet
Thanks for the help in advance guys

Apparently two different pistons were spec'd to be used depending upon how the block measured at assembly. The 'B' pistons are 4/10,000 larger in bore size. I think you would have to look at what you have to know the proper replacement.. they have either no stamp on the skirt for 'A' or a 'B' stamp.
