The 61st International 500 Mile Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana on Sunday, May 29, 1977. Considered one of the most historically significant editions of the Indianapolis 500, several sidebar stories complemented the unprecedented accomplishment of race winner A. J. Foyt. Foyt became the first driver to win the Indianapolis 500 four times. As of 2015, Foyt's record has been tied by Al Unser and Rick Mears, but still stands as an Indy record. It was this race that saw the last time the winning car had both a body, and engine built entirely within the United States.
