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.
There were 28 American-born drivers in the entire racing grid; Buddy Arrington received credit for the last-place finish after his car overheated on the second lap. There were 420 laps in this race. They were completed in more than two and a half hours with Darrell Waltrip defeating Benny Parsons by at least two laps in front of an audience of 20000 people.
Waltrip earned the pole position in qualifying for his fast qualifying run of 103.793 miles per hour (167.039 km/h); driving a 1975 Chevrolet Chevelle Laguna in that event. Only one caution flag was given out for a period of eight laps; two changes in the first-place position were made between Cale Yarborough and Darrell Waltrip.
Frank Warren was the lowest finishing driver to actually finish the race; being 47 laps behind Waltrip. Attrition took its toll again as only twelve cars were running at the end. Other notable drivers who raced included J.D. McDuffie, Richard Childress, Elmo Langley and Coo Coo Marlin. Monetary awards given out to this race ranged from $6,500 for Waltrip ($30,884.04 when adjusted for inflation) to $305 for last-place finisher Arrington ($1,449.17 when adjusted for inflation). Engine problems and overheating issues would cause many of the qualifying drivers not to finish the race.
