D1AE-6015-AC

D1 says it was FIRST used in 1971, there also will be a date code somewhere on the motor like a "4C26". The AC has nothing to with emissions, I think it has to do with revisions to the part number. AA would be the first casting. Number Dummy is the expert on this.

The AC is a suffix. It likely is just a revision number. Not sure whether you are looking at a casting number or a part number. D1 indicates initial design in 1971, A I believe is engine family, E means engine part, 6015 part type (as I understand it) and AC would be the current revision.
