[4] Walt began building dragsters with Art in 1952; their first car was a three-wheeler with an Oldsmobile six-cylinder engine, and an Oliver farm tractor green paint finish.
Arfons is also credited with being the first to incinerate a junked car with the exhaust from his jet dragster, in order to provide entertainment for the crowd at Indianapolis Raceway Park one year when the race had been rained out.
These were such crowd pleasers that he later built fiberglass-bodied jet funny cars, a Chevrolet Camaro, a Mercury Comet, and Ford Mustangs.
The car held the World Land Speed Record for three days during the battle between Art Arfons and Craig Breedlove.
In 1965, Walt Arfons built Wingfoot Express 2, which reached 605 miles per hour (974 km/h), but it did not qualify for an official record.
