Williams F-3s

The F3 uses motors with flat flywheels due to low clearance due to the die cast frame. F7 motors won't work in a F3.

Williams has made both F3s and F7s... Motors are the same but the trucks are apparently slightly different. When Williams offered power upgrade kits for their diesels the F3 and F7 power trucks had different part numbers.

Just the opposite. The trucks are the same, but the motors have different flywheels. As Gene already stated, that's because the F3 body has less internal headroom than the F7.
