The o after the D1 is the code for midsize car line the "E" stands for engine part. The 6015 is fords part number for a block and the last 2 letters are engineering codes.

It is a 1971 or later block. It could be a 1972, 1973, etc. depending on the part. A part manufactured in a given year often has older casting #s if it wasn't changed.
