Thank you all for the replies.
Yes, it’s a 1300, and not a 3100, late night typing error.
The valve cover has 2 acorn nuts on top of the valve cover.
8 head bolts visible on the drivers side of the head, haven’t taken the valve cover off yet.
So, did the 1953 Canadian versions all have 235 engines, or as I read, the head and block don’t match?
Noted above, April 53 head, but a February 54 block, you think it’s not original, Block switched at some point?
VIN tag says General Motors of Canada on it, and also made in Canada. This contradicts the Flint Michigan production, I’m confused?
How many Canadian 1953 trucks were produced, 401,710 seems like a lot of trucks for back then?
Just trying to better understand what I have, all replies and info. Shared, are truly appreciated.
