Have a bare Merc block, inside and apart since the mid 1970's. Comes with a Merc crank that needs a grind to clean up, full set of Jahn's pistons, head gaskets, intake gasket.
I know its missing heads and one main cap, oil pan, and not sure what else. Its a great start for a solid project but I just don't have the interest in this any more. Offering here before Kijiji. $350 takes it all. I'm north of Bowmanville.
