so i got my motor into pieces, and all looking good.
But i a friend of mine who knows a Little thinks my pistons are not the stock ones and seems like they are bigger than the OEM ones.

I don't know what size they are but I don't think they are anything bigger than the stockers or a 355ci.

how do I know the deference? and if there is any deference, how do I know what it is?

thanks in advince guys.

If your buddy is a ford guy they are probably stock. You can measure the diameter and figure out the displacement.

Our Stock pistons are fairly good pistons. Four Valve reliefes

Get out a mic. If it's exactly 4 inches, they're stockers

or somewhere on the piston you will see STD or some numbers on them like example .004
