Its in the front and its a ford system. With a milatary and a j-20 I would think it has the 401. All three blocks are the same size 304 360 401. You can tell witch one your looking at by crawling underneath, the engine size is welded on the block above the motor mounts. Can you tell I was a jeep fan long before being slaped up side the head and tought corectly. I still have a jeep but its my street vehicle. Wyatt

 

Over the years, the military has operated many different truck brands. In the 60s there was a militarized version of the Jeep J-series trucks that was in service called the M715. It was very different from the civilian versions. They had canvas tops, a completely different bed. Oversized tires and opened up fenderwells to accomadate the tires. The M715 used the "Tornado" 230 I-6 engine.

Usually most branches of the military have been pretty uniform on the trucks they use. An Army CUCV was identical to a USMC CUCV, to a Navy CUCV, however the Air Force has been known to use trucks not found in use in other branches. I would think that a later 70s or 80s Jeep J20 w/ a V8 would most likley be an USAF vehicle if one was ever used. I do know that there were a number of Cherokees were used as basic transportation vehicles, in the 80s but never to be used in combat. (They reminded me of forest service vehicles ) The M715s were used during Vietnam, a large number of them were damaged from enemy action.
