Nashville Speedway was converted to a half-mile paved oval in 1957, when it began to be a NASCAR series track. The speedway was lengthened between the 1969 and 1970 seasons. The corners were cut down from 35 degrees to their present 18 degrees in 1972.
The race itself took two hours, fifty-one minutes, and forty seconds from the first green flag to the checkered flag. Benny Parsons was the race winner with an average speed of 87.49 miles per hour (140.80 km/h) while the pole position winner Darrell Waltrip had a speed of 103.643 miles per hour (166.797 km/h) and finished the race in 3rd place. Cale Yarborough led the race with most number of laps (275) and was the points leader after the race for the NASCAR Winston Cup Series championship.
