Hi all, i'm hoping someone can help me work out what year flathead motor I have picked up. From what info I have come across, I think it's a 46 to 48 motor, reason I say that is because of the distributor style, it's not a "divers helmet" or "crab style" and it's not the later 8ba. The only markings I can see on bellhousing is a number 6 & just above that on a raised circle are the numbers 1 10 8. And above that on the rear right corner of the manifold there is the letter "J" stamped but nothing else. It also has aluminum heads with "made in Canada" on it. Hopefully someone has seen these numbers & letters (or lack of) before & can let me know if my guesses are right on it being a 46 to 48 model. And I am in Australia if that helps in the deciphering any. All help appreciated, Cheers, Moon.
