Following the production of the film, Sacks continued to drive for Hendrick's research and development team on a part-time basis in 1990. Sacks attempted two races (1 DNQ) in the No. 46, twelve in the No. 18 with sponsorship from Ultra Slim Fast, and three in the No. 17 as a substitute for Darrell Waltrip. Sacks earned a second-place finish at Talladega in May, and a pole at Daytona in July. The team was shut down and Sacks released at the end of the year, due to Slim Fast ending its sponsorship.
