The 1977 Firecracker 400 was a NASCAR Winston Cup Series race that took place on July 4, 1977, at Daytona International Speedway in Daytona Beach, Florida.
For the first time since 1949, three women raced in an official NASCAR Cup Series race: Italian Lella Lombardi, Belgian Christine Beckers, and American Janet Guthrie. Lella Lombardi was the only woman to score points in F1 and NASCAR. Lombardi is actually the only F1 driver ever to have a career total of less than one point. One driver scored one-seventh of a point in one season (for sharing a fastest lap, recorded only down to the second, with six others) but scored 51 more in other years.
