NASCAR's new compact car category debuted at the Daytona International Speedway on January 31, 1960. The first of two races was a road course, which used a portion of the high-banked tri-oval together with a twisting infield road for a lap distance of . The race length was 10 laps, . Averaging a speed of , Marvin Panch drove his Hyper-Pak into first place; all the Hyper-Paks swept the field taking the first seven places. The second race of the day used only the tri-oval track, 20 laps on its full length totaling . A multi-car accident on the fourth lap took out the four Valiant leaders including one driven by Richard Petty. Panch was not among them because car trouble delayed his start and he was busy passing slower cars from the rear of the field when the leaders crashed. After a restart, Panch worked to first place and stayed there, averaging a speed of . The remaining Valiants placed 1-2-3 and Panch again went into the winner's circle.
