Hi, I am Mike, welcome. I'm reviewing your question.

Expert:  Mike S. replied 3 months ago.

Engine can also be identified by engine identification (ID) number. Number is ***** on front of cylinder block, immediately forward of right cylinder head or on left side of cylinder block, on engine-to-transmission mating flange.

If the number is ***** on the front flange and it should be there, perhaps someone did like they did on my engine and when they shaved the block surface, they machined them right off and didn't bother to make a note of them and stamp then back in after the machine work.
