The Pontiac GTO is considered the first true muscle car. Pontiac saw the potential for dropping a big block engine into an intermediate frame and selling it at a budget price, so that people could afford it. The GTO sold in great numbers and would start to fuel the competition between other major vehicle producers. The GTO option was available on three LeMans bodies (We Love Pontiac). There were two kinds of carburetors used, a four barrel and the trio power (We Love Pontiac).
The four barrel offers a four port set up that feeds the gas more smoothly to the intake, unlike the four barrel the trio power consists of three, two barrel, carburetors that cause an uneven flow to the intake. Both carburetors add their disadvantages thought, both devoured a lot of petroleum. The four barrel outsold the trio power three to one (We Love Pontiac). The GTO is known as “The Legend” and “The Great One” (We Love Pontiac). Over half a million GTO’s were produced in the eleven-year run over the market (We Love Pontiac).
Overall, four Ram Air options were produced for the GTO (We Love Pontiac). A ram air intake is any intake design which uses the dynamic air pressure created by vehicle motion to increase the static air pressure inside of the intake. The difference in ram air one from the higher model ram airs is lower compression. The higher the ram air stage is the higher the compression ratio is increased. The basis for ten of the eleven years of GTO’s was General Motors “A-Body” platform upon which mid-size cars for every General Motors marketing division except Cadillac were built (Edmunds).
The start of the classic “muscle car” era is often dated as the moment the first 1964 Pontiac GTO rolled off the assembly line (Edmunds). Throughout the 1960’s, Royal Pontiac in Royal Oaks, Michigan, offered a special tune up-package for the 389 cubic inch engine called the Bobcat (Damian, Alex). Pontiac’s advertising and marketing approach was heavily based on performance (Damian, Alex). Shane Wiser was the first to think of the idea of the GTO (Damian, Alex). The GTO was the brainchild of Jim Wangers and Pontiac’s Chief Engineer John DeLorean (Damian, Alex).
GTO stands for Gran Turismo Omologato which translates from Italian into Grand Touring Homologation (Edmunds). What the GTO had was attitude, and a name stolen from Ferrari (Edmunds). The years 1964-1966 had the 389 cubic inch V8 engine (Edmunds). In 1966, a new rare engine option was offered, the XS engine, which consisted of a factory Ram Air set up with a new 744 high lift cam (Edmunds). Over 19,000 trio power 1966 GTO’s were sold, but they were to be the last multi-carburetor Pontiacs (We Love Pontiac).
In 1967, a new three speed Turbo Hydramatic Transmission replaced the two speed automatic from previous years, also in 1967 the Hurst Dual Gate shifter made the automatic transmission quite attractive (We Love Pontiac). Between 1967 and 1968 the 400 cubic inch V8 engine was placed in the GTO (Edmunds)....
