Over the years, Myrtle Beach Speedway has been the training grounds for some of NASCAR's biggest stars including Jeff Gordon (former Busch Series track record holder). All four generations of Pettys (Lee, Richard, Kyle, and Adam) and three generations of Earnhardts (Ralph, Dale, Dale Jr., and Kelley) have taken a green flag around the asphalt oval that spans 0.538 miles (0.866 km).

Rambi Raceway opened as a dirt track in 1958.

The track hosted one NASCAR Convertible Series event in 1958 and one NASCAR Grand National East Series race in 1972.

NASCAR Southeast Series had run 17 races at the facility between 1991 and 2004, with the Myrtle Beach 400 Late Model race (originally an All Pro event) beginning in 1993. Originally a 400-lap touring race, the race settled to NASCAR-specification Late Models of 250 laps with heat races and support races combined for 400 laps, originally set for Thanksgiving weekend, but later moved to the week before Thanksgiving in order to allow competitors to participate in the NASCAR Late Model Thanksgiving Classic at Southern National Motorsports Park in Lucama, North Carolina.

The NASCAR Busch Series race (the Myrtle Beach 250) in 2000 was the last major NASCAR event at the track.
