The 1997 AC Delco 400 was the 30th stock car race of the 1997 NASCAR Winston Cup Series and the 33rd iteration of the event.

In the final laps of the race, Petty Enterprises driver Bobby Hamilton would manage to make a late-race charge to lead to take his second career NASCAR Winston Cup Series victory and his only victory of the season.

In 1969, the track was extensively reconfigured to a high-banked, D-shaped oval just over one mile in length.

Bobby Labonte, driving for Joe Gibbs Racing, would win the pole, setting a time of 23.365 and an average speed of 156.696 miles per hour (252.178 km/h).
