The 1970 Plymouth AAR ‘Cuda was not your typical muscle car. It was designed with modest-engine racers in mind, built to compete on twisting road courses. One of several performance versions of the Plymouth Barracuda, the AAR was powered by 340-cubic-inch V-8 that made 290 hp. That was a pretty small engine by period muscle-car standards, but was required for SCCA homologation. Power was sent to the rear wheels through a 4-speed manual transmission.
