The 1964 Pontiac GTO, the muscle car that made other cars hit the gym, was GM’s rebellious child, sneaking past the company’s racing ban by appearing as a “power option package” for the Tempest. With a roaring 389-cubic-inch engine and options like the tri-power carburetors, this beast was as subtle as a neon sign in a library. Add a Bobcat power kit for a cheeky horsepower boost, and you had a car that would do 0-60 in 6.6 seconds, making speed limits seem like mere suggestions.
