Help Identifying My Block

[oldschoolford82]

I recently purchased a 302 block and I am trying to figure what it came out of. The stamping on it is D4DE-6015-AA. If what information I have is correct, it came out of a 1974 Falcon. However, the Falcon ended its reign 1970 ½ . Any help would be great.

E4DE castings lasted until 1978...... Falcon/Maverick/etc. Keep in mind that '87+ Mustang blocks have the E7TE (truck) casting #.
