The 1966 Pontiac GTO Convertible is one of the most celebrated muscle cars from the golden era, defining the segment for a generation. This particular GTO takes that legacy and enhances it with significant powertrain modifications. Acquired as a rolling project in 2019, this convertible underwent a comprehensive refurbishment. The result is a clean, aggressive package. It maintains the classic GTO look while benefiting from a powerful, updated mechanical core. This car represents a powerful, custom-built interpretation of a true American icon.
Body Refurbishment and Exterior Details
The iconic bodywork of the GTO received careful attention during the refurbishment process. The seller confirms that both doors and quarter panels were replaced to ensure a solid foundation. Following bodywork, the car was fully repainted in a vibrant shade of red. Exterior features include stacked headlights, a functional hood scoop, and GTO badging. The car retains its convenience with a power-operated white soft top and a power antenna.
Wheels, Brakes, and Suspension
The GTO rides on classic Cragar S/S 15-inch wheels, providing an authentic muscle car aesthetic. These wheels are mounted with BFGoodrich Radial T/A tires for a period-correct appearance and reliable grip. Power steering is included, which improves low-speed maneuverability significantly. Stopping power is enhanced by power-assisted front disc brakes, an important safety upgrade from the original specification. Rear braking is handled by traditional drums.
Interior Customization and Comfort
The cabin adheres to a classic black and white color scheme. It features front bucket seats and a rear bench upholstered in white vinyl, contrasted by black carpets. For a more focused feel, the car is equipped with a B&M shifter. While maintaining a vintage look, it includes modern audio enhancements. These features include a retro-look stereo, amplifier, and trunk-mounted subwoofer.
Driver Instrumentation and Controls
The driver interacts with a three-spoke steering wheel and a classic woodgrain dashboard fascia. Instrumentation includes the factory 120-mph speedometer and a fuel gauge. Performance monitoring is enhanced by an aftermarket AutoMeter tachometer. Additional gauges for vacuum, oil pressure, coolant temperature, and voltage are mounted conveniently below the dashboard. Approximately 2k miles have been added since the completion of the refurbishment work.
Engine Specifications and Performance Build
This GTO is powered by a powerful Chevy 454ci LS6 crate V8 engine, installed previously in 1985. The engine is fueled by a Holley carburetor and breathes through an Edelbrock intake manifold. Ignition is reliably handled by an MSD system, and cooling is managed by an aluminum radiator and twin electric fans. Four-into-one long-tube headers feed into an X-pipe exhaust system with Flowmaster mufflers. Exhaust cutouts are also included, allowing the driver to unleash the full sound of the big-block V8.
Drivetrain and High-Performance Components
Power is efficiently routed through a high-performance TH400 three-speed automatic transmission. The transmission features a 2,200-rpm stall-speed converter. It was professionally modified by Freddy Brown Performance in New York for robust and quick shifting. The engine’s raw output is confidently delivered to the rear wheels via a durable 12-bolt rear axle. This axle features a limited-slip differential and aggressive 3.73:1 gearing, ensuring strong launches and responsive acceleration.
