1960 Buck & Thompson Slingshot Dragster

As automobile racing speeds increased, repurposed dirt horse tracks became inadequate. In the 1910s promoters turned to wooden boards, which provided a smooth road surface and were less expensive than bricks or concrete. But rotting wood required frequent replacement. Improvements in concrete and asphalt made board tracks obsolete in the 1930s. The 1.25-mile board track at Altoona, Pennsylvania, operated from 1923-1931.

This is Henry Ford's first race car. After his first auto company failed, Ford turned to racing to restore his reputation. He raced "Sweepstakes" against Alexander Winton on October 10, 1901, and, to everyone's surprise, the novice Ford beat the established Winton. The victory and resulting publicity encouraged financiers to back Ford's second firm.

Mason Colbert placed third with this car in the 1939 All-American Soap Box Derby national championship in Akron, Ohio. The first official derby was held in 1934. Young contestants built their cars from soap boxes, orange crates, and baby carriage wheels. Over the years, designs became more elaborate and materials more sophisticated. But the "fuel" remained the same -- gravity.

Hale Barber and Clarence Warnock established the Barber-Warnock Ford dealership in Indianapolis in 1917 and were active supporters of the Indianapolis 500 race on a 2.5-mile oval track originally paved with brick and one of the most popular and well-known races in the country. In the mid-1920s, Barber-Warnock moved from fans and supporters to participants by sponsoring specially built Model Ts. In 1924, Barber-Warnock entered three "specials" built by the Chevrolet brothers -- Louis, Gaston, and Arthur -- under the Frontenac name. Although fairly powerful and fast, the "Fronty Fords" were no match for the rest of the field, finishing a disappointing 14th, 16th, and 17th.

When machinist George Montgomery started racing in 1953, all drag racers were amateurs with "real jobs" supporting their hobby. This car helped change all that. Montgomery bought an old Willys in 1958 and built a dragster so successful that promoters started paying him to run at drag strips nationwide. In 1966, Montgomery became one of drag racing's first full-time professional drivers.
