1971 Nova Parts and Restoration Information

dscf1183

Introduced in 1971, the Rally Nova was a new offering for buyers who wanted the appearance of a muscle car, but without the hassles associated with owning a muscle car during this era of increased insurance premiums and fuel scarcity.

Many manufacturers were forced to lower the compression on their powerful motors from previous model years, due to new requirements for unleaded fuel and increased fuel efficiency, which drastically reduced horsepower and torque ratings. Rather than focus on performance, the Rally Nova was a loud statement that featured full racing stripes, Rally Nova stickers and badging, as well as Rally wheels. Overall, 7,700 Rally Novas were built during 1971.

Another popular Nova model for 1971 was the Super Sport. Although there were minimal changes to the styling between 1970 and 1971 (such as the removal of the front fender vents), the overall performance of the Super Sport also took a hit as Chevrolet had removed the optional big block 396 V8 from the Nova lineup.

Despite this change, Chevrolet still produced 7,015 Super Sport Novas during the 1971 model year. However, overall sales were down from the 19,558 Super Sports produced for 1970, likely a combination of the many factors at play during this transitional period of the American automotive industry.
