77 Ford F-250 Was told it is a high boy? Military drivetrain? Looking for info on identifying drivetrain components. Divorced transfer was told it had a 460 but new valve cover gaskets say 400?

I have just obtained this truck. It has 8 lug 16.5x18.5x44 Super Swampers. It has some type of hydraulic steering assist and hydraulic stabilizer (looking to try to identify).

You can pick your passion around here. The majority of all places, I am probably not supposed to be in, being that it is Fort Knox property but there trucks and tanks can really create holes your truck can temporarily disappear.

Any info on identity of drivetrain components.
