At the final race of the 1950 NASCAR season, in Hillsboro, Bill Rexford had a slight points lead and battled with Roberts for the championship. Rexford nearly cost himself the title, when he had an early engine failure. Roberts was able to win a championship with a top 5, but he drove aggressively and tried to win. His own engine gave out with less than 50 laps to go, giving Rexford a dramatic and controversial championship. It was his best year in NASCAR and he picked up the only win of the season and of his career in this car, at Canfield Speedway in Ohio.
