8CM is Merc from 49 thru early 51. Some Canadian Manufactured stuff has C included in part numbers but the Y in there is a mystery to me.

If it's important, why not just call the guy and ask?, he gives his phone number in the listing.

8cy= 8 cylinder....it`s a common abbreviation...it`s like V8 255c.i .when referring to capacity.

The 3 3/4" stroke (239) & 4" stroke(255) pistons are different so it is important.

I called, they are 3.1/16 + .030 early ford v8..mistery solved .Great starting price for a set of pistons, to bad they were so small
