The 1963 Daytona 500, the 5th running of the event was held on February 24, 1963, was won by Tiny Lund driving a 1963 Ford. Lund drove his number 21 to victory in three hours and 17 minutes. 

Weather played a role in Tiny Lund winning this race; with temperatures reaching up to 75 degrees.  Lund won by making only four pit stops, but he would not have been able to make the distance on four pit stops had the first ten laps not been run under caution. Had the race not started under caution, Lund would have had to make five pit stops.  He was able to win on four pit stops along because of the slow start time.
