Charlotte Motor Speedway, a 1.5-mile (2.4 km) quad-oval track located in Concord, North Carolina, was the location for the race.[2] The track's turns were banked at twenty-four degrees, while the front stretch, the location of the finish line, was five degrees.[3] The back stretch, opposite of the front, also had a five degree banking.[3] During the 1968 season, Charlotte Motor Speedway hosted the NASCAR Grand National Series twice, with the other race being the National 500.
Designed and built by Bruton Smith and partner and driver Curtis Turner in 1959, the first World 600NASCAR race was held at the 1.5 mi (2.4 km) speedway on June 19, 1960. On December 8, 1961, the speedway filed bankruptcy notice. Judge J.B. Craven of US District Court for Western North Carolina reorganized it under Chapter 10 of the Bankruptcy Act; Judge Craven appointed Robert "Red" Robinson as the track's trustee until March 1962. At that point, a committee of major stockholders in the speedway was assembled, headed by A.C. Goines and furniture store owner Richard Howard. Goines, Howard, and Robinson worked to secure loans and other monies to keep the speedway afloat.[4]
By April 1963 some $750,000 was paid to twenty secured creditors and the track emerged from bankruptcy; Judge Craven appointed Goines as speedway president and Howard as assistant general manager of the speedway, handling its day-to-day operations. By 1964 Howard become the track's general manager, and on June 1, 1967, the speedway's mortgage was paid in full; a public burning of the mortgage was held at the speedway two weeks later.[5]
Smith departed from the speedway in 1962 to pursue other business interests, primarily in banking and auto dealerships from his new home of Rockford, IL. He became quite successful and began buying out shares of stock in the speedway. By 1974 Smith was more heavily involved in the speedway, to where Richard Howard by 1975 stated, "I haven't been running the speedway. It's being run from Illinois."[6] In 1975 Smith had become the majority stockholder, regaining control of its day-to-day operations. Smith hired H.A. "Humpy" Wheeler as general manager in October 1975, and on January 29, 1976, Richard Howard resigned as president and GM of the speedway.
This race was shortened to 255 laps due to rain after being able to race for three hours and four minutes in front of 60,000 people.[7] Rain had started to appear much earlier in the race but flagman Johnny Bruner would not wave the caution flag until the conditions got dangerous.[8] Throughout the day, 0.32 inches of rain were reported around Charlotte Motor Speedway.[9]
Darel Dieringer would be a part of the race's second crash on lap 212; giving him a 32nd-place finish.[7]Earl Balmer, Paul Lewis, and Phil Wendt would retire from NASCAR after this racing event.[10] Prior to this race, Balmer was known as the winner of the 1966 Daytona 500 qualifying race.
