Clessie Cummins and the Cummins workforce pose with the No. 8 car that ran in the 1931 Indianapolis 500. The Cummins Special qualified for the race with an average speed of 97 mph. Two days later, with Dave Evans behind the wheel, it became the first entry ever to run the entire race nonstop, finishing 13th on just $1.40 worth of “furnace oil.”
