Of the 3,783 1970 GTO convertibles built, 241 were equipped with the 455/automatic powertrain, according to Pontiac Historical Services. This example was originally finished in Atoll Blue (28E), and it was repainted during the aforementioned refurbishment, at which time a replacement Sandalwood convertible top was installed. The car features a rear wing, GTO badging, and a hood-mounted tachometer.
Rally II 14″ wheels are mounted with 215/70 BFGoodrich Radial T/A tires showing 2017 and 2018 date codes. Braking is provided by power-assisted front discs and rear drums. A Firestone spare tire is located in the trunk.
The cabin has been reupholstered in Sandalwood vinyl (257) with matching carpets and woodgrain trim, with parts supplied by Ames Performance Engineering of Spofford, New Hampshire. Equipment includes front bucket seats and a rear bench, a woodgrain steering wheel, air conditioning, a center console, an AM/FM radio, and a clock.
Located inside the 140-mph speedometer is an odometer that shows 41k miles, less than 100 of which were added by the selling dealer. True mileage is unknown.
The optional YA-block 455ci V8 produced a factory-rated 360 horsepower and 500 lb-ft of torque when new. A Ram Air hood helps feed the four-barrel carburetor.
Power is sent to the rear wheels through a rebuilt Turbo Hydramatic 400 three-speed automatic transmission. Additional photos of the underside are provided in the gallery below.
Highlights from a photo collection showing the extent of the car’s refurbishment are presented in the gallery along with more than 40 pages of receipts.
