455-Powered 1966 Pontiac GTO Hardtop Coupe 4-Speed

This 1966 Pontiac GTO is a red-over-black hardtop coupe that was refurbished before it was acquired by the selling dealer in 2026. It is powered by a 455ci V8 paired with a four-speed manual transmission, and further details include Holley Sniper electronic fuel injection, an Edelbrock intake manifold, long-tube exhaust headers, power-assisted front disc brakes, power steering, a hood-mounted tachometer, a 442-style Hurst shifter, and staggered-diameter Cragar S/S wheels. The cabin is outfitted with front bucket seats, a heater, and a Pioneer cassette stereo. This GTO is now offered by the selling dealer in North Carolina with a Pennsylvania title.

The body was refinished in red from the factory shade of Nightwatch Blue (E) under prior ownership, and exterior elements include white pinstriping, stacked headlights, a simulated hood scoop, a hood-mounted tachometer, dual side mirrors, and chrome finishes on the bumpers, grille, rocker panels, and window trim. The selling dealer notes paint imperfections.

Chrome 14″ front and 15″ rear Cragar S/S wheels are mounted with Goodyear Eagle GT II white-letter tires. The car is equipped with power steering and revised rear shocks and springs. Stopping is provided by power-assisted front discs and rear drums.

The front bucket seats and a rear bench are upholstered in black vinyl and are joined by color-keyed door panels and carpeting. Appointments include a 442-style Hurst shifter, a heater, lap belts, and a Pioneer cassette stereo. A Holley EFI module is found in the glove compartment.

The wood-rimmed steering wheel frames a 120-mph speedometer, an analog clock, and a fuel gauge. Auxiliary readouts for oil pressure and water temperature are mounted below the dashboard. The five-digit odometer shows 3,400 miles, approximately 50 of which were added by the selling dealer. Total mileage is unknown.

The 455ci V8 was installed under previous ownership and is fitted with a Holley Sniper electronic fuel injection system, an Edelbrock intake manifold, chrome valve covers, and long-tube headers. The engine was reportedly overhauled before it was installed.

Power is sent to the rear wheels through a four-speed manual transmission and a 10-bolt rear axle, which the selling dealer states has a limited-slip differential. Work under prior ownership is said to have included resealing the transmission and rear differential.
