(Inman would win an eighth championship as crew chief in 1984 with Terry Labonte). While the 1981 season gave Petty 3 wins, he felt the season was a failure, and the Regals being ill-handling and poor in reliability. For 1982, he made the move to the Pontiac Grand Prix, with the promise of substantial factory support from Pontiac. 1982 was a repeat of 1978, and no victories were to be had. At first, the Grand Prix behaved much like the Dodge Magnum of 1978, with handling and speed problems. Toward the end of 1982 things improved with several top-10 finishes, which opened the door to a successful 1983 season with three victories, and several top-5 and top-10 finishes. In 1983, he broke his 43-race winless streak from 1982 with a win in the 1983 Carolina 500, barely edging out a young Bill Elliott. After a controversial win at Charlotte in October 1983 (recognised by NASCAR as win No. 198), Petty left the race team his father founded for the 1984 season. He spent '84 and '85 driving for Mike Curb before returning to Petty Enterprises in 1986. Because of the 1971 Myers Brothers 250 combination race in 1971 that Petty finished second in a Grand National Car while winner Bobby Allison drove a Grand American car, there is a technical dispute regarding which race is credited as his 200th win. NASCAR did not credit Petty with a class win, which was a dispute that affected two other drivers, Elmo Langley and Charlie Glotzbach, both of whom drove in combination races that season finishing second to Grand American cars. Under modern NASCAR combination race rules for various series, Petty would be credited with that would be recognized as his 135th win. On May 20, 1984, Petty won what under modern regulations would be recognized has his 200th Cup class win, the Budweiser 500 at Dover International Speedway, when the Winston-Salem class win is recognised. On July 4, 1984, Petty won his officially-recognized 200th (and what would turn out to be his final victory) race at the Firecracker 400 at Daytona International Speedway. The race was memorable: On lap 158, Doug Heveron crashed, bringing out the yellow caution flag, essentially turning lap 158 into the last lap as the two drivers battled back to the start-finish line. Petty and Cale Yarborough diced it out on that lap, with Yarborough drafting and taking
