Modified 351-Powered 1966 Ford Mustang Fastback 5-Speed

Description

Carroll Shelby’s performance GT350, created to meet the Sports Car Club of America’s rules for entry into the B Production class, fulfilled the Mustang’s potential as a competition car and became an instant legend. While Shelby built 562 GT350s for 1965, including 34 GT350R race cars, the following model year brought nearly 2,400 more GT350s. Even that production increase wasn’t enough to quench the thirst of automotive enthusiasts.

Considering the limited availability of authentic Shelby GT350s, builders often create tributes in an attempt to duplicate the cars’ good looks and performance. This one, based on a 1966 Ford Mustang, has been modified in the style of a GT350, albeit with added underhood punch, a 5-speed manual transmission, and more.

In addition to the 351ci V8 — bored and stroked to 396ci — that replaced its original 289, the car has a Cobra-style oval air cleaner, an aluminum intake manifold, Cobra NDA valve covers with additional gaskets used to clear rockers, forged flat top pistons, Racing Head Service (RHS) aluminum cylinder heads, MSD distributor, and numerous additional mechanical modifications. A T5 5-speed manual transmission directs power to the rear wheels.

The engine bay also has a Monte Carlo bar for stiffness, along with polished export brace components and chrome shock tower tops. The car rides on 17” wheels, while braking is handled by later Mustang-sourced front discs and rear drums.

The fastback body has been refinished in white with red striping, an aftermarket grille with twin central lamps, a hood scoop, and various GT350 and Cobra badges. Additionally, the car features aftermarket wheels, while its red-trimmed interior features Pony bucket seats, a wood-rim steering wheel and shift knob, and a custom center console with cupholders.

This modified 1966 Ford Mustang Fastback is now represented by a Broad Arrow Specialist and is now offered with a clean North Carolina title in the current owner's name.
