Is that a #10 or #11 and does it have a Jimmy or an Allis-Chalmers motor?
I'm not sure if it's a #10 or a #11. I was told it's the equivalent of a D8.
The engine says GM on it and it's bigger than 2 BBC's.
I put the plow truck battery that I used to get the Massey started in it today
and it turned over just fine. I don't want to try to start it until I pull the drain plug to see if there's water in the crank case (the oil is showing a couple quarts over full) Here's a picture of one that looks a lot like it but of course there's no way to reference size
