Low-mileage, two-owner 1966 Belvedere II with original 426 Hemi, Certicard, and broadcast sheet offered in preserved condition.
A highly original 1966 Plymouth Belvedere II 2-Door Hardtop, factory-equipped with the legendary 426 cubic-inch Hemi V8, has surfaced with just 15,118 miles on the odometer and a well-documented two-owner history. Offered with its original Certicard and broadcast sheet, the muscle-era survivor is a rare glimpse into Chrysler's horsepower revolution of the 1960s.
Delivered new with the then-new street-spec 426 Hemi—capable of producing 425 horsepower and 490 lb-ft of torque—the Belvedere II represents one of the earliest factory applications of the second-generation Hemi in a B-body platform. This particular example, painted in factory-correct Tuxedo Black with a blue vinyl interior, was kept by its original owner until 2018 and remains largely untouched aside from routine maintenance and a professional engine build by Steve Schmidt Racing.
The powerplant has since been dyno tested at 465.5 horsepower. The date-code correct dual-quad Hemi is backed by the correct A727 TorqueFlite automatic transmission and sends power through a Suregrip-equipped 8¾-inch rear axle with 3.23 gears. While the engine shows signs of needing a minor tune-up, the car retains remarkable drivability and originality, including plastic-covered seats and period-correct finishes throughout the interior.
Outside, subtle styling cues and dog dish hubcaps reinforce its sleeper status. The single-stage paint remains presentable, though some minor imperfections, including edge wear and small chips, are noted. Underside preservation efforts by the original owner included the application of electric motor paint, which still lingers on the frame rails.
Despite some surface rust on the exhaust and minor cosmetic blemishes, the car is reported to be structurally sound and mechanically complete. Recent service items and accessories, including the original wheels and tires, car cover, and a case of 25W50 racing oil, will accompany the sale.
As one of the few surviving factory Hemi Belvederes with such low mileage and original documentation, this 1966 example stands as a true black-on-black unicorn in the Mopar collector world—a muscle car icon hiding in plain sight.
