"The Butterball Special started life in Great Britain as an experimental four-wheel-drive vehicle of inventor Archie J. Butterworth. Butterworth started with the chassis from a four-wheel-drive Jeep and a 3,700-cc air-cooled Steyr V-8 engine. The engine was bored to 4,500-cc and Butterworth set compression at 14:1. Equipped with a special camshaft, two Amal carbs, and running on alcohol, the motor produced a very respectable 250 horsepower. Butterworth raced the car in England in sprints, hillclimbs, and road races between 1948 and 1951. In 1949 and again in 1951, Butterworth ran the fastest time of the day at the Brighton Speed Trials. Later in 1951 at the Shelsley Walsh Hillclimb, Butterworth crashed the car badly. After the crash, Butterworth sold the car to the Ameican Foul-Wheel-Drive-Company, which imported it to the United States."
