7.3 or 7.4L?

I was just underneath replacing the rear trans seal and decided to check the Engine ID.
Is this a unicorn engine or are there other 7.4L's out there? Eng. ID# 7.4JU2U3490291. At the oil change
it does take 4 gallons not 14 Qts.as others have indicated. Any one have similar numbers?

7.4 is a GM 454 V8 gas engine.
ford only had the 7.3 diesel from 88 to early 03 in pickups.

What does the 7.4 in the engine number refer to?
