	Rahmoc's debut in NASCAR came in 1978 competing in two events, at the NAPA National 500. Mock drove the No. 75 Chevrolet to a 26th-place finish. He also ran the Dixie 500at Atlanta, finishing 24th. Mock ran the 1979 Daytona 500 the next year, but finished 35th when he was involved in a wreck not of his making early in the race. After the Daytona wreck, Mock ceased driving and Rahmoc had several different drivers. Some were, Lennie Pond at Atlanta & Daytona, Bobby Brack at Charlotte, and Bill Elswick for numerous races, his best finish being 16th at Richmond. Harry Gant drove in 1980 for the team at Riverside International Raceway, finishing twelfth and Texas world Speedway, finishing tenth. Elswick returned over the next eleven races, and the team also picked up sponsorship from his Performer Boats Company. John Anderson, Chuck Bown, Joe Millikan, and Elswick finished out the year. Millikan came back in 1981, but was replaced after the Gabriel 400 by Tim Richmond. Richmond got his first top 10 finish in that event at Nashville Fairgrounds Speedway. Gary Balough drove for the rest of the 1981 season.
