D1=1971
Z = Mustang
M =Ford Motorsport SVO (this would be a service replacement or a crate motor)
6015= Basic part # for finished engine block
AA= change level. Starts with letter A (original tooling) then uses every letter of the alphabet except "I". when all 25 letters are used, They start over with AA.

Find the Date Code located on the passengers side, below the deck above the starter.

The date code will tell you when the engine was actually cast. It should look like this "6B24" Which means it was cast in the 5th year(of the decade in the first set of numbers)2nd month, and 24th day, February 24, 1986 for example.
