318 engine identification

HM318R 3736 1?68 H = 72 M = Mound Rd plant R = reg fuel

The 3736 is the build date = Oct 20 1971

1?68 would be the unit that day

I don't think it's out of a truck

Thanks! That's what i thought but wanted to confirm since the guy i bought it from said it was a 74. Just wanted to investigate and find the right answer. Gonna be awhile til it gets any attention but it was nice to step away from body work for a minute. lol
