The 1966 World 600, the 7th running of the event, was a NASCAR Grand National Series race held on May 22, 1966, at Charlotte Motor Speedway in Charlotte, North Carolina. Contested over 400 laps on the 1.5 mile (2.4 km) speedway, it was the 20th race of the 1966 NASCAR Grand National Series season.
Marvin Panch of Petty Enterprises would win his final NASCAR Grand National Series race while Gene Cline would retire from professional stock car racing after the race was over.[1] When Buddy Baker suffered a blown engine during the 44th lap,[citation needed] he was setting a pace of 145.291 miles per hour or 233.823 kilometres per hour; speeds that were unprecedented during the late 1960s.
