David Pearson defeated Cale Yarborough by three car lengths in front of an audience of 46,000.^[2][4] There were 17 lead changes and three cautions for 20 out of the 200 laps.^[2] The race took two hours and fifty minutes.^[2][4] Richard Petty earned the pole position with a speed of 158.569 miles per hour (255.192 km/h), the average speed of the race was 141.148 miles per hour (227.156 km/h).^[2][4][5] Joe Frasson finished last due to an engine problem on lap 2.^[2] All 36 of the drivers on the racing grid were American-born males.^[2] The field was dominated by Chevrolet vehicles as opposed to Ford and Mercury vehicles.^[2][4][5]

Cale Yarborough dominated most of this race, with radio announcer Ken Squier saying it was one of the best runs he'd seen Cale have, but in the closing stages it was David Pearson out front and cruising to a win when a late caution came out for Coo Coo Marlin's blown engine while he was running seventh in the closing laps. Under the yellow the leaders all pitted with Yarborough regaining the lead only for Pearson to pass him on the backstretch after the restart and take the win. Overall it was still a good day for Yarborough as he capitalized on a 74-point swing in the point standings to vault back into the points lead as a result of Benny Parsons' issues.^[2][4] He would eventually become the 1976 NASCAR Winston Cup Series champion.

Bobby Allison was running second very late when he was black flagged for the Penske team having put tape over parts of the grill of his Cam 2 #2 Mercury. That aerodynamic improvement was illegal at the time but later became commonplace. Allison still recovered to finish third in part due to how few cars were left on the lead lap and the late caution.^[2]

The grand total of this race's prize purse was $105,355 ($596,087 when considering inflation).^[5]

Although the race is not televised by either CBS or ABC, the rare films and archived radio coverage (commentated by Ken Squier) of the race is included in a video for NASCAR's segment called "Retro Radioactive" during the franchise's 75th anniversary in 2023.^[6] The video also included the rare archived radio chatter between the racers and their crew chiefs as well as the radio voice of Competition Director Bill Gazaway, which captured his words "We do not run tape on the outside of the car." as he spots Bobby Allison's car having tapes in the grill. Allison's archived radio voice was also captured in the video as he was talking to owner Roger Penske to "put newspaper on the grill to make the car run faster."
