Model History

The 1966 Ford Mustang GT K-Code Convertible represents one of the rarest and most exhilarating versions of Ford’s groundbreaking pony car. While the Mustang was already a sensation, offering style, affordability, and customization, the K-Code package elevated it into true high-performance territory.

At its core was the legendary 289-cubic-inch “Hi-Po” V8 engine, rated at 271 horsepower. Designed with a solid-lifter camshaft, heavy-duty valve springs, forged pistons, and a stronger crankshaft, the K-Code was engineered for serious enthusiasts who demanded both speed and durability. Unlike the standard Mustang, this model was built to perform reliably under spirited driving, making it a favorite among those who wanted race-inspired engineering in a street-legal car.

The GT Equipment Group added rally-style instrumentation, front disc brakes, fog lamps, and dual exhausts, enhancing both the Mustang’s performance and its striking presence. Combined with the convertible top, the result was a car that delivered exhilarating open-air motoring without sacrificing refinement or control.

Produced in extremely limited numbers, the K-Code Convertible remains a coveted collector’s piece. It captured the essence of the 1960s driving experience—youthful freedom, performance, and individuality—while standing as a testament to Ford’s ability to blend engineering excellence with timeless design.

Brief Description

This 1966 Mustang GT convertible is a rare and highly desirable example of Ford’s first-generation performance heritage. Equipped with the ultra-rare K-code 289 High-Performance V8, this engine was factory-rated at 271 horsepower and featured solid lifters, a high-flow intake manifold, larger carburetor, and dual exhaust. Only a small percentage of total Mustang production received the K-code option — fewer still were GT convertibles paired with a 4-speed manual transmission and luxury interior.

Finished in its correct Arcadian Blue over parchment Pony interior, this Mustang is as visually striking as it is mechanically significant. The factory GT equipment group includes front disc brakes, dual exhaust with rear valance trumpets, fog lights, special GT badging, and handling upgrades.

Restored in meticulous detail by noted Mustang specialist Fred Glazier Jr., the car retains its original factory drivetrain, original buck tag, and original build sheet, adding to its authenticity and documentation pedigree. Every component was restored to concours-correct specifications, making this car a reference example for collectors and enthusiasts alike.

This Mustang has also been proudly displayed at the prestigious Simeone Foundation Automotive Museum, further underscoring its historical significance and overall quality. With its rare factory options, documented provenance, and outstanding restoration, this K-code GT convertible stands as one of the finest surviving examples of Ford’s performance legacy in the Mustang lineup.
