Tried this question on a couple of Chevelle sites but no answers. Hoping maybe one of you Beaumont guys know the answer. Trying to decipher anything out of a engine ID stamping of 21 (space) 6634224. I know the engine was removed from a 66 SD that I took off the road in 72. The casting number is 3858180. Anything I see on the net shows ID stamps as a combination of letters and numbers but mine are numbers only.

Any info is greatly appreciated
Thanks
Canadian engines used the numbers for Id of what car it belong to. US engines letters and numbers show plant, date of assembly and hp tranny info
