The Junk Formula

In 1929, a set of rules known as the "junk formula" was introduced to the Indianapolis 500. Designed to open up competition and lower costs, the new rules outlawed superchargers, increased engine displacement, and reinstated the riding mechanic. Here, driver Russell Snowberger examines the Studebaker President inline eight-cylinder engine in his "Russell 8" car that finished 8th in the 1930 race.
