The Engine in a Ford GPW
The engine in a Ford GPW is known as the “Go Devil” engine. It is a straight-4 automobile engine that was made famous in the Willys MB and Ford GPW Jeeps produced during World War II. The Go Devil engine powered nearly all the Jeep vehicles built for the U.S. and its Allies during the war. The Ford GPW and Willys MB jeeps had basically identical underhood views, but closer inspection of the engine block serial number would indicate if the engine was originally from a Willys or Ford.
Differentiating a GPW from a Willys MB
To differentiate a GPW from a Willys MB, you can check the engine block for a serial number starting with either “MB” or “GPW” to identify the motor. On earlier models, the left side of the rear panel has “Ford” or “Willys” stamped into it. Additionally, the rear wheel well tool boxes have either a rectangular depression (Ford) or a circular depression (Willys) where the lock button is installed.
Identifying Your Ford GPW Engine
If you have a Ford GPW engine and want to determine its age, you can look for the engine block serial number. The serial number can provide clues about the engine’s production date. For example, a late production block with a casting date of June 21, 1945, could indicate that the engine was manufactured around that time. However, it’s important to note that over the years, motor pool mechanics, government rebuild depots, and civilian owners have swapped parts between Willys and Ford jeeps, so it’s possible that your vehicle may have a combination of the two types.
