40 drivers competed in this 334-lap racing event in front of a live crowd of 80,000 ardent NASCAR followers.

Butch Mock would become the lowest-finishing driver to complete the entire event; albeit 80 laps behind the competitors in the lead lap.
Bobby Allison would defeat Darrell Waltrip after nearly three hours and thirty-two minutes of racing; Allison swept the weekend as he also won the World Service Life 300 Sportsman race. The margin between the victor and the second-place finisher would be slightly more than half a minute. There were 40 changes in the lead position throughout the racing event; with Bobby Allison, Cale Yarborough and Richard Petty dominating a fair amount of these laps.
