Sunday 8th July 1973
Benny Parsons used help from relief driver John A. Utsman to win the Volunteer 500 at Bristol Motor Speedway, Tennessee, US. Utsman recalled in a 2010 article on NASCAR.com that he drove nearly half of the 500-lap race in what would be Parsons’ only win at the Tennessee track. Despite the extra time to make the driver change, Parsons was still credited with finishing seven laps ahead of runner-up L.D. Ottinger. Cecil Gordon came home third.
