1939 Mack BX

Engine Type:
128 Horsepower 519 Cubic Inch Gasoline with Overhead Valve

Transmission Type:
Straight 5-Speed

Truck Information:
Mack made their BX model from 1932 until 1940; 15,000 of them were built. The BX was the largest of the early B-series of Mack trucks. This 1939 Mack BX was purchased new by the George Atwell Foundation Company in New York City. It is believed to have been purchased to help haul steel beams and other equipment for completing construction on a portion of Radio City Music Hall. In 1985, Tom Spencer purchased this Mack and completely restored it. The body, the engine, and the chassis are all original from 1939, the first year Mack used this engine model. While this specific engine uses gasoline, the same block was used in the soon-to-follow 519 Lanova which was Mack's first ever diesel engine. This truck does not have a sleeper, but the BX was the first Mack to offer sleepers as an option. There are four-wheel brakes on this truck. The original top speed was 35 miles per hour, but with some gearing changes, it could go over 50 miles per hour. The extra speed along with the sleeper made this a good truck for cross-country hauling. There's a winch on the back of the truck that is typical of what would have been found on a truck in that era. The Iowa 80 Trucking Museum purchased this Mack from Tom Spencer in 2011. Top Speed: 35 MPH (Original) / 52 MPH (Current)
