help decoding a ford 68 block

I've decided to tear into and engine thats been sitting in the garage for a year or so...getting heat from my girlfriend about "finishing what you started." :) It's stamped as follows: C8OE-6015A code 8E20 here's the question as I decoded it:

C=1960s era
8=1968
O=fairlane/torino
E=engine, engineering
6015=??????
A=289/302 cid

8=1968 stamping
E=month of May
20=20th day

Is it possible that Ford, in Metuchen, NJ, had put a engine slated for a fairlane/torino into a mustang with a C-4 tranny? Is this common place in mid-year production models? or did the mustang the engine/tranny combo came out of suggest a donor history, ie. non-numbers matching :) Thanks for any help

C8OE-6015A

The 6015,center number, four or more numbers or letters, is the part number.

The A at the end of the number indicates that the part is the first version. If it was revised once, it would be B. If it was revised again, it would be C, and so on. When they run out of letters, it becomes AA, AB, and so on.
