In 1964, the Healey Competition Division entered 767 KNX for the 12 Hours of Sebring, driven by Paddy Hopkirk and Grant Clark. It is also acknowledged to be the Works car which returned to Sebring in 1965. This time it was to be driven by Paul Hawkins and Warwick Banks, who took an incredible victory in torrential conditions.
After its success at Sebring, the car was sold to the Yorkshire woolens magnate and privateer racer Henry Crowther, who used it for hill climbs and sprints, before selling it to his friend Ted Worswick in late 1965. He competed in numerous Motorsports events, most notably the 1966 and 1968 Targa Florio. Ted finally sold the car in the mid-1990s after nearly 30 years of ownership to Norman Grimshaw, who continued its successful racing career with his co-driver Whizzo Williams. In 2006, it was imported to the United States to its current home in Virginia.
Recently, the car has had a major mechanical rebuild by marque specialist Denis Welch Motorsport, Staffordshire, England (including a complete engine rebuild with a new, fully balanced steel crank, rods, etc.) and it is ready to go. It has had just 6 owners from new and is regarded as the most original Works Healey to survive, retaining its original body and engine.
