Pontiac GTO 1964 - 1967

The first Pontiac GTO was an option package for the Pontiac Tempest, available with the two-door coupe, hardtop, and convertible body styles. The US$295 package included a 389 cu in (6l) V8 rated at 325 bhp (242 kW) at 4800 rpm.

The Tempest line, including the GTO, was restyled for the 1965 model year, adding 3.1 inches (79 mm) (7.9 cm) to the overall length while retaining the same wheelbase and interior dimensions. It sported Pontiac's characteristic vertically stacked quad headlights. Overall weight increased about 100 pounds (45 kg). Brake lining area increased nearly 15%. The dashboard design was improved, and an optional rally gauge cluster ($86.08) added a more legible tachometer and oil pressure gauge.

The 389 engine had revised cylinder heads with re-cored intake passages, improving breathing. Rated power increased to 335 hp (250 kW) at 5,000 rpm for the base 4

The GTO underwent a few styling changes in 1967. The louver-covered tail lights were replaced with eight tail lights, four on each side. Rally II wheels with colored lug nuts were also available in 1967. The GTO emblems located on the rear part of the fenders were moved to the chrome rocker panels. Also the grill was changed from a purely split grill, to one that shared some chrome.
