It’s hard to imagine that the GTO might never have made it into production. Had it not been for a small group of managers at Pontiac who were also car enthusiasts and visionaries, the GTO might not have been. This small group was prepared to fight the battle on three unique fronts.

The first and perhaps most important battle was with the United States Justice Department. During the early 1960s, General Motors was so large it captured nearly 60 percent of the domestic car market. Just as they did with the Standard Oil Company, the Justice Department was prepared to break up The General if their market share exceeded 60 percent. Incredible as it may seem, GM was purposely trying to slow down vehicle sales in an effort to thwart such an action. The second front occurred on January 24, 1963 with the killing of the Super Duty Group that was responsible for Pontiac’s dominance in both NASCAR and drag racing. The third front was getting the car approved by corporate bean counters, and the legal staff who initiated a policy that limited GM cars to ten pounds per cubic inch.

Pete Estes, Divisional Manager of Pontiac, and John Z. DeLorean, Pontiac’s Chief Engineer, were devising their own plans to get the car launched–regardless of who wanted it stopped. They were keenly aware of the youth market, and were determined to build something unlike any other performance car. Now they had to find a way to convince (some would say trick) the corporate stogies into building the car.

All of the 1964 mid-size cars were entirely new. Gone was the unibody, replaced by the traditional body-on-frame design. The new vehicles were sleeker and longer, and the full frame allowed a larger engine to be installed between the framerails. That’s just what DeLorean and the gang wanted to do. There was, however, one problem. The ten-pounds-per-cubic-inch issue. Stuffing the 389 into a Tempest would defy the corporate edict. By using the “better to ask forgiveness than permission” philosophy and knowing that the staff honed in primarily on unique models, the GM hot rodders decided the GTO would be an option instead of a unique model, the W62 option to be exact.

Checking off the W62 box changed the mild mannered LeMans into a tire-melting muscle car by using Pontiac’s 389 cubic-inch engine, topped with high-output 421 cubic-inch heads and a Carter four-barrel carburetor. A Tri-power option became available midyear and increased horsepower to 348. Other components of the GTO included a three-speed manual transmission with floor-mounted shifter, heavy-duty suspension, special hood with twin faux hood scoops, and GTO emblems on the front, side, and rear of the vehicle. Other fun options included quad exhaust tips, two versions of the Muncie four-speed trans, or a two-speed automatic and a garden variety of rear axle ratios.

With all of the potential for the upcoming GTO, there was still one problem, Frank Briggs. Briggs was the Pontiac Sales Manager and not a fan of the GTO. His opinion was that the GTO wouldn’t sell and it would wind up sitting on dealer lots. Unbeknownst to upper management, Estes and DeLorean pre-sold 5,000 units. Briggs had to give in.

The GTO came in three body styles: two-door-post coupe, two-door hardtop, and convertible. Customers received a GTO by first ordering a LeMans at a cost of $2,776 (coupe) then ordering the W62 package for an additional $295.90. The total price for a GTO coupe was $3071.90. A plethora of options were also available to increase the dealer profit on each car.

By year’s end, the GTO was an incredible success–sales of 32,450 showed that Estes and DeLorean were correct. The youth market was about to explode, and Pontiac was poised to give them exactly what they wanted.

Engine – The basis for the 389 cubic-inch engine started with the 1955 model. In general it’s a dependable powertrain, with the main weak point being the wear-prone nylon camshaft gear. The engine takes well to performance mods and can fend for itself against Chevrolet, Ford, and Chrysler performance cars.

Handling – With a stiffer suspension than the LeMans, the GTO was near the top of the list when it came to mid-size handling. All GTOs came with a front stabilizer bar that lessened the effect of its heavy V-8.The car was designed for straight-line acceleration, and road handling ultimately took a back seat.

The first true American muscle car started a culture that continues to exist today. Pontiac took a chance on an unknown, and with the vision of a few key people brought excitement to the car business. The GTO stands out as the catalyst for that excitement. Owning a “Tiger” is as close as you can get to screaming “hot rods forever” out your driver-side window.
