Other finishers in the top ten were Bobby Allison, Benny Parsons, Dick Trickle, Lennie Pond, Buddy Arrington, Elmo Langley, Cecil Gordon, and Henley Gray. The time of race was 03:26:58. The margin of victory was 1.4 seconds. The average speed of the event was 145.24 mph. The pole winning speed was 158.315 mph.
After it was discovered that Charlie Glotzbach, the first driver to qualify for first pole position, had improperly modified his restrictor plate, Glotzbach's team was fined $500. David Pearson, who had initially qualified second, was then awarded first pole. Glotzbach appears in several images in the collection.
