I really don't know. I was told this was a stock 406 motor. It may have been a truck engine.
I didn't spend a lot of time checking numbers on the parts when I tore it down, just wanted to make sure it wasn't junk. Then we stuffed a 350 in the truck and the motor got put off to the side. I'm cleaning out some stuff and it's on the list.
I'd like to try and sell it but I'm not sure where to list it and as what.
Hate to junk a motor that old.
