1970 American 500

Twenty thousand people watched Cale Yarborough win the race which lasted 4 hours, 14 minutes, and 24 seconds.^[2] The average speed was 117.811 miles per hour (189.598 km/h) while the pole speed was 136.496 miles per hour (219.669 km/h).^[2] There were seven cautions that lasted for forty-six laps and the margin of victory was four seconds.^[2] As the penultimate race in NASCAR's Grand National era, this race was crucial for people wanting to win the 1970 NASCAR Grand National Championship. Bobby Isaac finished the race in 7th place, good enough for him to clinch the championship.^[3]

492 laps were completed on the paved oval track spanning 1.017 miles (1.637 km).^[2] The winner's purse was $20,445^[2] ($165,540 when adjusted for inflation) while last place (40th) paid $540^[2] ($4,048 when adjusted for inflation). Drivers who were eliminated from the race had to deal with engine problems, crashes, transmission problems, and problems with their fan pulley (in addition to their rear end).^[2] Pete Hamilton would drive in his final race for Petty Enterprises here while Cale Yarborough would complete his final race for the Wood Brothers. Future winning team owner Hoss Ellington would retire from driving after this race.^[4] Cale Yarborough would eventually transfer himself to the USAC Indy Car Series in 1971.^[5]
