The 67th Indianapolis 500 was held at the Indianapolis Motor Speedway in Speedway, Indiana, on Sunday, May 29, 1983. After finishing second three times, winning the pole position twice (1977–1978), and being the fastest qualifier one additional time (1981), Tom Sneva finally shook his "bridesmaid" status and won his first and only Indianapolis 500. The win also represented the record seventh Indy victory that chief mechanic George Bignotti was involved with.

The 61st 500 Mile International 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 2023, Foyt's record has been tied by Al Unser Sr., Rick Mears and Hélio Castroneves, but still stands as an Indy 500 record. Foyt's victory is also the last time the winning car was built entirely within the United States.
