An entirely new family of V8 engines was offered. The six-cylinder was still available, but rarely ordered -only 355 were built. The base V8 was the with a 2-barrel carburetor, while a pair of V8s were optional: a 2-barrel that ran on regular-fuel, as well as a high-compression (10.2:1) premium-fuel version with a 4-barrel carburetor and dual exhaust that produced at 4800 rpm and of torque at 3000 rpm. An entirely new four-link, trailing-arm rear suspension system was introduced eliminating the previous torque tube design.
