Sorry I couldn't get to the engine to take a picture of the number stamped on it, but I will later today or this weekend. In this case V1210THC.
It is not a "serial number" for the engine, think of it as a "batch number". The POP lists the block number, which identifies the engine, what plant it was built, and what type of vehicle it was installed in and even a date code as well.

To answer your question, a similarly ordered truck, ordered at the same time could have similar block numbers. Nothing individually identifies it as part of an individual truck.

Correct, the engine listed in the POP is not part of the VIN, or other individual identification number. The POP lets you really narrow the field down to a certain batch of engine blocks. Just for simplicity's sake, it's like narrowing 50 million small block engine possibilities down to only 10,000.
