1972 Pontiac GTO Parts & Accessories

1972 Pontiac GTO

The GTO was born from modest roots. The first-generation Pontiac Tempest ran from 1961-1963 and was badged based on option packages as “LeMans” for the sportier Tempest. In 1964 the Tempest was redesigned to share the intermediate A-body platform with other GM divisions, thus shedding its compact roots as well as the quirkier engine and driveline approaches. John DeLorean was head of the Pontiac division, and he wanted to add performance to help burnish Pontiac’s image. Dropping a 325hp 389ci engine into a Tempest as a low volume high performance option was the answer. He named it GTO, which some say stands for “Gran Turismo Omologato”—the racing homologation group in Europe, while others say it stands for “Grand Tempest Option.” Either way, with three-two bbl carbs and weighing almost one-pound per horsepower, it had both the looks and beef. Though projections were for 5,000 units, by the end of 1964 the GTO option was ordered by 32,450 customers. There was even a Top 40 song called “Little GTO” by Ronnie and the Daytonas. With revised styling that included stacked headlights and increased output to 360hp, Pontiac more than doubled GTO sales in 1965, selling over 75,000. 1966 saw a major restyle and the GTO became its own model, not a Tempest option. By 1967 the 389ci engine had increased bore bringing it up to 400ci, while Hurst shifters, four-speed transmissions, exposed tachometers mounted on the hood, and disc brakes made the GTO a legend. With the new A-body platform launched in 1968, the GTO got the curvy body and its own body-color “Endura” urethane grille, making the 1968 and 1969 front ends very distinctive. GTOs were called “tigers”, and some affectionately called them “goats”, but Pontiac called its special GTO “The Judge”. Ordering this package got you a “Ram Air III” engine, mag-like wheels, Hurst shifter, wider tires, and a rear spoiler. Oh, and screaming decals that announced your arrival. 6,833 were built in 1969. More organic styling arrived in 1970, while the GTO got another unique urethane body-color bumper. The 455ci big block Pontiac could now be ordered with the highest output rated at 370hp. The GTO saw another revised front end in 1971, and 1971 would be the last year for the convertible. 17 Judge GTO convertibles were built, making them the rarest GTO ever made. 1972 saw the downward spiral of the muscle car as emissions and safety mandates from the government, plus ever higher insurance rates increased both the price of purchasing, and cost of maintaining a car like the GTO. Almost 5,000 GTOs were built in 1973 on the new “Colonnade” A-body Pontiac used for the last GTO on the intermediate platform. 1974 was the last year for the original GTO, applied as a performance and handling package for their Ventura compact.

1972 GTO

The final year for this A-body platform saw the 1972 GTO go back to an option package for the Tempest. Only 646 cars were found for the high output 455 HO engine rated at 300hp. The GTO convertible was dropped for 1972. Sales also dropped, down to around 5,800 GTOs built. This was the last year for this version of the A-body platform. It would return in 1973 in a completely different form.
