The Muscle RevolutionLuxury wasn't as important as absolute speed for Detroit carmakers in the late 1960s. Cars were designed to be as powerful as possible at a reasonable cost. Of course, this competitive environment fostered very specialized street machines. The Legendary ContenderThe Plymouth Road Runner put itself on top in 1969. It employed an aggressive design with a “no-nonsense” make and model, specifically designed to take on the local drag strips. The drivers soon realized the amazing racing qualities. Massive Engine PowerA huge 440-cubic-inch V-8 engine was under the hood. This was a potent power engine, coming with a substantial 390 horsepower. The vehicle got off the starting blocks with tremendous violence, due to the amount of torque. Stripped For SpeedPlymouth stripped other comfort features from the car to make it lighter, and the interior was drier too. A light-weight lift-off fiberglass hood, which was previously steel, was installed. This extreme miniaturization had a great impact on the power-to-weight ratio. Blistering Track PerformanceThe car recorded an astounding 13-second drag race from 0 to 1/4 mile. This performance beat almost all of its modern rival factory cars. Set a new record with showroom drag cars. Dominating Drag StripsIt was a natural phenomenon that was popular with both amateur and professional drag racers because of its immediate reliability. It was the number one competitor in head-to-head races with rival muscle cars. The car developed fearsome track respect. Innovative Induction SystemsThe engine was fitted with a special triple 2barrel carburetor system called the Six Pack. This setup was an optimum arrangement for fuel delivery in a wide open throttle acceleration. It gave immediate throttle response. Engineering The ChassisChrysler engineers added substantial suspension parts to the car. Rear axles were upgraded and strong, reliable brakes took the crazy stress. Maximum power delivery was achieved this way.Rare Production NumbersThere is a limited number of these special A12 packages produced in Plymouth. The few surviving specimens are much sought after by collectors today. It is very difficult to find an original model these days. Enduring Automotive LegacyThe car is still a classic testament to the raw American performance style. It had changed the performance car game forever with its quarter mile numbers. It was a historic machine that set a generation.
