The 1966 Ford Thunderbird 428 Convertible represents the final year of the popular fourth-generation “Flair Bird” styling. Only 5,050 convertible Thunderbirds were produced that year. This particular example is highly significant due to its optional 428ci V8 engine. It offers a commanding combination of open-air style and genuine big-block performance. The car has been refurbished, ensuring its presentation remains strong. As such, it is an appealing option for collectors seeking a powerful, mid-sixties convertible.
Exterior Style and Distinctive Features
The car originally left the factory finished in the unique shade of Honeydew Yellow. It has since been repainted, maintaining its cheerful factory color. A key feature is the power-retractable black soft top. The exterior boasts a wrap-around chrome-finished front bumper and iconic quad headlights. Distinctive details include gun-sight front turn signals. Sequential rear turn signals and full-width taillights provide a recognizable rear view. The overall design epitomizes the jet-age styling prominent in the mid-1960s.
A Black Interior with Unique Comforts
The interior is finished in black vinyl upholstery, covering the shell-contour front bucket seats and curved rear bench. The driver’s seat is power-adjustable, a great luxury feature for the era. The Thunderbird features a unique swing-away steering wheel, simplifying entry and exit. Additional amenities include power windows and an AM/FM radio. The MagicAire heater/defroster system provides climate control. However, potential owners should note the reported noise from the air conditioning compressor.
Power, Engine Specs, and Performance
Powering this Thunderbird is the optional 428ci V8 engine. This big-block engine is fitted with a four-barrel carburetor. From the factory, this V8 was conservatively rated at 345 horsepower and 462 lb-ft of torque. This substantial power is sent to the rear wheels via a C6 three-speed automatic transmission. The car is also equipped with a desirable limited-slip differential. This provides improved traction and performance compared to an open axle. The large V8 delivers effortless acceleration and highway cruising ability.
Upgraded Driving Dynamics and Maintenance
For enhanced safety and control, the car is equipped with power-assisted front disc brakes and rear drums. This setup improves stopping power significantly. Power steering comes standard, making low-speed maneuvers easy. Recent maintenance includes the replacement of the battery in 2024. The left window regulator was also recently replaced. These steps help ensure the car remains functional and reliable for its next owner.

Its rarity is enhanced by the factory-optional 428ci V8 and limited-slip differential.
