In 1955, the Mercury Outboards team of Carl Kiekhaefer were virtually untouchable. The team, running Chrysler 300s, saw the likes of Buck Baker, Bob, Fonty, and Tim Flock, Frank Mundy, and even Junior Johnson spend time behind the wheel of their machines during their brief history. Kiekhaefer is one of the stranger owners in NASCAR history, with questionable ethics and team orders running rampant throughout his small time in the sport. By 1957, he was gone, citing differences with NASCAR, who had refused his ideas for rule changes, all of which would have likely favored his teams.
In this vehicle, Tim Flock roared to a remarkable 18 wins, 18 poles, and 32 Top-10 finishes, eventually being crowned the champion at the end of 1955.
