ford vs mercury piston differances?

[tony1947]

I'm collecting parts for my 52 v8 flatty that I hope to put into my 46 pickup ,no chevy crap for me! Anyways I have a Mercury 1952 engine with a 4" crank I think,well I believe it is,anyways I have 2 sets of pistons and need specs on how to tell if either are mercury pistons. I know the wrist pin is set up some in the merc. pistons but how much? and is there an ez way to tell? pictures? thanks in advance , tony in buffalo ny

If you have have some wrist pins out of the pistons, I wonder if you could measure them with a micrometer. I need the size for a project I am working on.
