Since its debut for the 1964 model year, the GTO has been one of the most popular and collectible cars on the market and has been featured in many popular television shows and movies including Gone in 60 Seconds, Kojak, and The Big Steal. One of the most collectible years is that first year -- 1964. The one-year-only styling for the front gives it some uniqueness, while plenty of options ensured it lived up to its performance image. Among the options was the ability to upgrade the engine from the standard 4-barrel version to a more powerful and throaty “Tri-Power” version. Checking off that option would swap out the 389 cubic-inch V8's single four-barrel carburetor for an exotic triple two-barrel carburetor setup.
