The Cup regulars returned to Dover in June 1972 for the track's first of two races of the trimmed Winston Cup schedule. The Mason-Dixon 500 once again turned into a race between the two drivers who had claimed all of Dover's previous trophies.

Coo Coo Marlin lined-up third in his first ever Dover start. He actually laid down the same timed lap as Allison. Because Allison qualified first, however, Marlin was bumped back to the third starting spot. At the time, the fast lap became his top career starting position. He later qualified second at Talladega in 1976.
Allison won the 1971 Mason-Dixon 500 in a Holman Moody Ford. After several years of a strained business partnership, John Holman and Ralph Moody finally divorced at the end of 1971. Allison joined Richard Howard's Chevy team with its cars prepared by Junior Johnson. Moody joined Dover as a Vice President and assisted many drivers with set-ups for the race - primarily independents such as James Hylton, Soapy Castles, and British driver Jackie Oliver in Junie Donlavey's Ford.

The race was the 31st of 51 career times where Allison and Petty finished in the top two spots.
