I see the big "75" cast by the Distributor hole, so I'm betting that date is A155, or Jan 15, 1975. Hard to tell for sure in the pic, maybe hard to tell in person as well. Try a wire brush over the casting date and see if it doesn't become more of a '5' at the end.

It seems unlikely to me to be cast with the big number 75 by the distributor and be a 76 engine, which A156 would be.
