weird uses for a slant 6

Anybody see unusual uses for a slant six. Popped the hood on one of our airport tugs that had a stuck choke, and low and behold there it was the leaning tower of power. This thing is geared rediculously low to pull small aircraft around. Its coupled to a 2 speed tranny. Powerglide i presume. At about 3000 rpm it rolls at 20 mph.

Doesnt have to be in a vehicle, could be stationary power supply, boat engine, etc.
