I thought it signified the year the part entered service. A part entering service in say 1967 could stay in production for years.

    C7ME-A   is a casting number that relates to a manufacturing blueprint. Casting numbers typically stayed the same until manufacturing revised the part. Many parts kept their respective casting numbers for many years , especially crankshafts and rods. These castings were revisions of the C6ME ( revised by Mercury division) that "was" formerly a  C5AE casting number. The "Mercury" changes didn't affect the Ford usage so Ford Division used the "ME" castings.
     The casting date is independent of the casting number for obvious reasons. Parts have casting dates before the year of the casting number ( like a C7ME block with an OCT-DEC '66 date) as well as after in the case of your '72 cast C7ME block.
    Similar situations include the Boss 302 and 429 engines.

It would need to be a C6ME-A with an A scratch to be for a 67 production and the casting date should be ABOUT 3 weeks before the Ford build date.

2A16 would be January 16, 1972. To be a 68 428 block it needs a C scratch and C7ME-A. If it has no big C scratch mark then it is a 390 block.

At some point "service" 390-427-428 blocks got stripes cast into them also. My '72 427 block had the stripes. It was a service block.

 This was close to the time that the casting of FE blocks was moved to the NEW Michigan Casting plant and the "mirror image" 105 was put on the front of the block. The ribs were added to the casting patterns as a repair measure to the very old ( by then) core patterns so they could be used for a few more years.
