Stamp on 67 390 Block

I have a stamp on a 390 block out of a 67 Mustang S-Code. The Stamp is on the small vertical pad close to the deck at the rear of the driver side. The first two characters are 7F, which I would take to mean the year '67 and "F" for the Dearborn plant where the engine was assembled. The last two characters I can't make out. Is there any rhyme or reason to these stamps?

I was under the impression that some hi-performance '67 cars have a stamp at the back of the block on the pad below the cylinder head, not the area where this stamp is.

The engine casting date is early June '67 and the car was built in San Jose in late June. The engine might have been out of the car and might not be original to the car. The heads have Certainly been off, and the oil pan has what looks like the CJ or SCJ windage tray.
