original 389 CI Tri-Power V-8 topped by three 2-barrel carburetors

With fresh looks for the 1966 model year and a handsome Montero Red paint job, this GTO convertible is an outstanding representative of what many consider to be the prototypical muscle car. John DeLorean and his Pontiac skunkworks crew created the big-engine-in-midsize-model muscle car template with the first Lemans GTO in 1964, a hit aided by clever marketing from drag racer turned ad man Jim Wangers. By 1966, the GTO was its own distinct model line. A face-lifted body, combined with a healthy array of powertrain options and more promotional work from Wangers, pushed sales that year to the GTO's peak of nearly 97,000 units—about 10% of Pontiac's total sales for the year.

This 1966 Pontiac GTO Convertible is equipped with Pontiac's standout engine: its correct, original 389 CI Tri-Power V-8 topped by three 2-barrel carburetors, a combination rated at 360 HP and 424 lb-ft of torque. For 1966, the center carb was enlarged to match the size of the other two for better drivability. This engine carries the WS designation, indicating it is paired with a 4-speed manual transmission, which is controlled by a Hurst shifter topped by a special wood-grain knob.

The dashboard, redesigned for '66, is also finished in wood grain, as is the rim of the optional Custom Sport steering wheel. The front bucket seats and rear bench are upholstered in Parchment-colored vinyl, which ties in nicely with the power-operated white convertible top. Amenities for the GTO's driver include power steering and an AM radio. The convertible rolls on redline tires that are mounted to Pontiac's Rally I wheels. All GTOs were equipped with heavy-duty shocks and springs, as well as a front stabilizer bar, making the GTO a real driver's car. The powerful V-8 in this one just adds to the experience.
