It was powered by a 169.5L (10,343 c.i.) 16 cylinder 3300 hp (2,460 kW) engine coupled to a generator. The generator then powered 4 electric traction motors located at each rear wheel. It is 66 feet (20 m) long and 22.6 feet (6.9 m) tall. It is 56 feet (17.1 m) tall with the dump box extended. Built in late 1974 at GM's London, Ontario Plant, it was to undergo 12 months testing in California.
