1977 Indianapolis 500
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 2025, 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 (both chassis and engine) was built entirely within the United States.
The race was sanctioned by USAC, and was part of the 1977 USAC National Championship Trail. After rain-shortened races in three of the past four years (1973, 1975, 1976), the 1977 race was run the full distance under hot and sunny conditions.
Two major stories headlined qualifying. During time trials, Tom Sneva won the pole position with a new track record. He became the first driver to break the 200 mph barrier at the Speedway. On the final day of time trials, Janet Guthrie broke the gender barrier by becoming the first female driver to qualify for the Indy 500.
During the summer of 1976, the entire track was repaved in asphalt. It marked the first time since the original brick surface was laid in the fall of 1909 that the Indianapolis Motor Speedway was repaved in its entirety. The surface was allowed to cure over the winter, and during a tire test in March, Gordon Johncock ran a lap of 200.401 mph, an unofficial track record.
This would be the final Indy 500 for track owner Tony Hulman, who would die of heart failure on October 27, 1977. IMS Radio Network anchor Sid Collins did not call the race for the first time since 1951. Collins committed suicide on May 2, just five days before opening day, after being diagnosed with ALS. Collins was replaced by new "Voice of the 500" Paul Page. Then less than a year later, eight USAC officials would be killed in a plane crash.
Other historical milestones during the month included the inaugural Pit Stop Contest, the first grandson of a former driver entering (Teddy Pilette), and the first father and son combination attempting to qualify for the same race (Jim and James McElreath Jr.). However, neither Pilette (grandson of 1913 competitor Théodore Pilette) nor McElreath Jr. succeeded in making the field.
For 1977, the turbocharger "boost" settings were increased from 75 inHg (used in 1976) back to 80 inHg (used in 1974–1975). This, along with offseason engine development by the teams, was expected to provide about 50 additional horsepower.
During the first week of practice, several drivers flirted with the elusive 200 mph barrier. Mario Andretti, A. J. Foyt, and Johnny Rutherford all ran unofficial practice laps over 200 mph. All three became immediate favorites for the pole position. Going into the month, the official one-lap track record was still 199.071 mph, set by Johnny Rutherford back in 1973.
