 There is something about Richard Petty and the number seven. He's one of three seven-time Cup Series champions. He has seven wins at Dover, and the victory in the 1981 Daytona 500 was his seventh and final in the Great American Race. Petty pulled away in the latter stages of the clash, besting Bobby Allison and Ricky Rudd to win the Harley J. Earl trophy. Number one.
