Pontiac expert and long-time writer Dave Bonaskiewich delves deep into the GTO model and its history, bringing the equipment and options of this iconic muscle car into full focus. He reveals the hardware under the sheet metal: the V-8 engines, manual and automatic transmissions, rear differentials, interior options, color codes, and so much more. When the GTO was released in 1964, it was offered as a unique performance package to the Tempest, and high-performance enthusiasts stood up and took notice.
Examined are the GTO's 4-barrel 389 with dual exhaust, 3-speed floor shifter, stiffer suspension, limited-slip differential, and heavy-duty cooling system. The 1965 GTO was restyled with more interior room being added, and the renowned 389 Tri-Power engine joined the lineup, cranking out 360 hp. By 1966, the GTO was a runaway success. Pontiac made the GTO its own model, and it featured a sleeker Coke-bottle styling.
A convertible joined the hardtop, and a pillared coupe also joined the lineup. The 1967 Pontiac GTO was arguably one of most the superbly styled models ever, with a wide range of engines and high-performance hardware. All of these important upgrades, advancements, and model evolutions are covered in exceptional detail.
