I have 3 /6 engines so far and I don't know what years they are. #1 has a ribbed v cover, drool tubes, 2463430-24 cast in the side, and c225 3 17 stamped on the pad by #1 and 3 core plugs. #2 has smooth v cover, 0 225 1 (101?) on the pad, 530-11 and2229 cast in side, no drool tubes and 5 core plugs. #3 has smooth vc, pt225 r 227 30199 on pad, 01127 and 2463430-18 cast in side. I think #1 should be a small register crank, but I'm not sure about #2 and #3. I tried the search but I must not know what I'm doing on that.

That tells me that #1 and #3 are 60-67 blocks and #2 is 68-75, however it dosn't tell me what year in that span. The # of core plugs is as much help as casting #s on that.
