Produced on Shelby American’s assembly line, the GT350 started out as a stripped-down K-code Mustang fastback before undergoing conversion into a Shelby. To differentiate the 1966 GT350s from their 1965 counterparts and to set the Shelby apart from regular Mustang fastbacks, exterior enhancements were implemented, including a fiberglass hood with a scoop, rear brake cooling scoops, C-pillar Plexiglas windows, and Guardsman Blue rocker panel stripes.
Shelby American also added a couple of upgrades such as Koni shock absorbers, rear traction bars, 15-inch wheels, a dash-mounted tachometer, competition seat belts, and a wood steering wheel. Additionally, the K-code 289 HiPo engine saw improvements, with its factory horsepower increased from 271 to 306 through the addition of an aluminum intake manifold, Holley 4-barrel carburetor, and Tri-Y headers.
This particular 1966 Shelby Mustang GT350, offered for sale on Bring A Trailer, is said to be the final GT350 produced for public sale in 1966 and the last fastback constructed for that model year, with only four 1966 GT350 convertibles produced for private distribution.
Ordered on August 19, 1966, chassis 6S2374 left the factory on September 29, 1966. Originally painted blue and equipped with a rear seat and radio, the car was first sent to Minnesota dealer Herb Tousley Ford. However, the dealer declined delivery, prompting the car’s return to the Ford Distribution Point in St. Paul. Subsequently, it was shipped to Chicago dealer Milo Brooke Inc., where it was purchased by its original owner on March 20, 1967. It changed hands in 1978, was repainted white by its second owner, and then stored until 2012.
Powered by a 289ci HiPo V8 engine mated to a four-speed manual transmission, this GT350 boasts Kelsey-Hayes front disc brakes, Koni shock absorbers, Magnum 500-style 14-inch wheels, black vinyl upholstery, a dash-mounted tachometer, and an AM radio. This 1966 GT350 is now offered sale as a non-running project and shows 60k miles on the odometer.
