    Hi, I'm no expert but I've been told the letters C & D castes on a block stands for the decade, c= 1960s and D = 1970 motor. The next digit is the actual year so your casting no. commencing with D4 means you have a 1974 ford V8 motor in your vehicle. I can't help with the other letters/ numbers.

    the block dates as 74 but the head dates are under the intake ports ,you may be able to see them with a small mirror with the intake off

    It's a 1974-based block, cast April 12, 1977. But the basic number is 6015, not 8015.
