The Mormon Meteor III was built in 1937 to handle the large Curtiss Conqueror airplane engine. It was built by both Ab's son Marv Jenkins and Augie Dusenberg. Ab sent Marv to build the car with Dusenberg at only age 17. This intimate knowledge of the Meteor III enabled Marv to complete the meticulous restoration that required most parts to be fabricated again from scratch many years later after his father Ab's passing. It had many unique features, such as the body offset by six inches on the frame to help the car turn on the track. In 1939, Jenkins drove the car 171 mph (275 km/h) and broke all of the 12-hour endurance records. The Mormon Meteor III set a 24 hour record of 161.180 mph (259.394 km/h) in 1940 that would not be broken until 1990.
