1971 Camaro Parts and Restoration Specifications
1971 was the year the car insurance industry brought an end to the original ‘muscle car’ era. In an effort to comply with federal regulations requiring leaded fuel to be phased out, General Motors lowered compression ratios of all engines to a maximum of 9.0:1. Not only did this actually cut horsepower (compared to an 11.0:1 engine), but General Motors also began rating their engines in SAE NET horsepower. In 1971, engines were rated in both SAE NET & Gross HP.
While essentially a carry-over from the previous year, the 1971 Camaro had several notable changes. These changes included a new 3 piece rear spoiler, optional ABS plastic front spoiler, high back seats adapted from the vega, and minor changes to the cars emblems. Little changes in the appearance of the 1971 Chevy Camaro separated it from the previous year, but under the hood the Camaro was a much tamer vehicle. New insurance laws and the woes of a faltering economy along with fears of oil shortages led General Motors and all U.S. based car manufacturers to downgrade HP in favor of better gas mileage and mainly to comply with new federal laws. 1971 was considered by many car enthusiast to be a very disappointing year.
