After a family move, Gary spent his High School years in greater Huntington, Indiana, where he attended Huntington High School, now Huntington North High, graduating around 1963. From an athletic family, Dilley's father John was a standout swimmer competing for Purdue University in the late 1940's, where he earned an NCAA title, before his collegiate swimming career was cut short by an injury to his shoulder. Gary's father John swam for Coach Dick Papenguth at Purdue, and excelled in backstroke competition, as would Gary.

After travelling to Tokyo with the team, Dilley represented the United States at the 1964 Summer Olympics, where he received a silver medal in men's 200-meter backstroke, with a time of 2:10.5, which would have been a world record, but he finished only .2 seconds behind American teammate Jed Graef. American Bob Bennett took the bronze with a time of 2:13.1, establishing an American sweep in the event. Dilley set new Olympic records in the heats and semifinals, but Graef improved upon Dilley's records in the event's second semifinal and final.
