A two-time series champion of the Cup Series, Flock was one of the sport's first dominant drivers. Flock had 39 victories in only 187 starts. His victory total still ranks 16th all time. Flock won his first series title in 1952 and had eight wins and 22 top-five finishes in 33 starts. Flock won his second series title in 1955, posting 18 wins and 32 top-fives in 39 races. Flock's 18 wins stood as a single-season victory record until Richard Petty surpassed it with 27 wins in 1967. Flock, who died on March 31, 1998, was named one of NASCAR's "50 Greatest Drivers" that same year.
