He reached the finals ten times that season, winning a record 42 rounds of competition. He qualified number one in all 14 events. His two-season streak ended at the 1988 Gatornationals with 22 straight top qualifiers. His 1988 season was similar to 1987. After struggling early in the season, he won five of the last seven races en route to his fourth straight title. He retired his Thunderbird after 19 national victories in favor of a Ford Probe at the Supernationals. The cars set a national e.t. record at 7.277 seconds, the quickest Pro Stock run in NHRA history. He used the Probe to win at the Fallnationals, which was his 67th career victory.
