The Amazing GTO, Muscle Car Unleashed
They say the Muscle Car Era started with 1964 GTO. By bypassing a GM ban against putting big engines larger than 330 cubic inches into small cars, Pontiac sneaked a 389-cubic-inch V-8 into its Tempest as an option called the GTO in 1964, according to MotorTrend.com.
The cars were extremely popular, which in turn made the GM Execs take notice.
This made it possible or muscle cars from all the GM divisions to be produced successfully.
The 1967 GTO was the first full model year of availability of ram air through a functional hood scoop on the GTO. It was a 400-cubic-inch V-8, delivering 360 horsepower and a neck bending 438 ft lbs of torque.
The 1967 model year required new safety equipment. A new energy-absorbing steering column was accompanied by an energy-absorbing steering wheel, padded instrument panel, non-protruding control knobs, and four-way emergency flashers. A shoulder belt option was also featured, and the brake master cylinder was now a dual reservoir unit with a backup hydraulic circuit.
