Agreed..but a 67' block just would be a cool find. Once I get my own eyes on it I will get dirty and go for the casting date.
The engine still has the exhaust manifolds on it so I will run those #'s to see what they are.

I hope it is, you know now where to look to fill in the gaps in Information. Just because it has an M doesn't mean they didn't build the first one there, and then moved to Windsor. it was a new design, and things were moving quickly. Mopar wanted to gang up on Ford and chevy with that engine. and they did.
it was a mystery motor to the gm and ford guys, and they were ticked when that little dart kicked ***. I also saw more than a few Roadrunner guys get their butts kicked by it as well. it was a terror on the street. I remember well!
