1966 Shelby GT350 Fastback

After a successful year with the 1965 GT350, Shelby American updated the model for the 1966 model year. The most noticeable changes were the new rear quarter windows and side scoops behind the doors.

Like the previoud year the 1966 GT350 had the K-Code 289 in³ V8 which offered 306 horsepower was kept as standard with a 715 Holley carburetor. The suspension was heavily modified with lowered front A-arms, Koni adjustable shock absorbers, larger front sway bars and a Detroit Locking rear end with traction bar brackets. The braking system also upgraded with larger Fairlane units. Other main features included a top-loader, 4-speed manual transmission and a heady-duty suspension all around.

Exterior modifications included a new fibreglass hood with a scoop and front pins. Down the sill of the car ran the GT350 graphic which was also used on the race cars. To finish off the race-inspired theme, the exhaust system was routed to the side of the car with Glasspak mufflers.

Inside, the GT350 had a removed rear seat and an extra center-mounted binnacle with oil pressure and tachometer gauges. Pete Brock designed a new Cobra center cap for the wood steering wheel and aircraft seatbelts were fitted.

1966 Shelby Mustang GT350 SCCA B-Production Racing Car 

Since 1999, the car has been in the care of the current owner, who began a full restoration in 2008 and has enjoyed the car enthusiastically, returning it to its 1967 Kneeland livery and fitted it with a correct B Production engine, featuring many original Shelby external and internal engine parts. It will surely prove to be a formidable vintage racing candidate for its next fortunate caretaker. As Motor Trend stated in one of its early road tests of the GT350, “We recommend it as a sure cure for all strains of boredom,” a statement that certainly applies to this example.
