Dan, Thank you for moving me to the correct forum. I took my best guess.
I didn't know how they designated model years back then. But given the fact that the war ended September of1945, and it is a second series, made me wonder if it had been assembled in November of 46. Very interesting stuff.
The 216cu. engine numbers match the 1952 title I have for it. And I would like to keep that block in the truck. But that leads me to lots of other questions. Mainly, Can I justify spending big money to have a babbit prounder reworked? I really don't mind the smaller engine. I just don't have any experience with them.
