1970 saw the introduction of the all new Second Generation Camaro. The 1st generation Camaro (1967 - 1969) was seen as a hasty response to the Ford Mustang. It was considered a compromise by some critics. There would be no compromises with this car. Due to production delays the 1970 Camaro was introduced in February 1970, half way into the production year. Because of this, some people will call the 1970 Camaro a 1970 1/2, but officially the car is a 1970 model year Camaro. Good things come to those who wait, and this car was met with rave reviews from nearly everyone. Chevrolet had a winner that would run for 12 years.
The 1970 Camaro was all new. It was longer (2.0"), lower (1.1") and wider (0.4") than the previous Camaro but still had a 108" wheelbase. It had a wider track (1.7" front, 0.5" rear). It's doors were longer (by 8") and the roof was moved back giving the car a sleek long hood, short rear deck which typifyed the pony-car. The convertible body style was no longer available. The windshield was swept back increasing visibility by 10% along with hiding the radio antenna within it (depending on radio choice). The rear view mirror was bonded to the windshield, no longer hung off the roof trim. The front subframe was redesigned to improve the structural integrity of the car. Efforts were made to eliminate road noise by strategically insulating various points on the car. The interior of the car was completely redesigned with a new dashboard, console & other interior trim.
The Camaro was also available with a distinctive appearance package called the Rally Sport (RPO Z22) option. Unlike the previous years hidden headlights, the RS package included a distinctive nose & bumper treatment, round front parking lights, hidden wipers and other trim. The Rally Sport package could be added to any model Camaro and when combined with the SS option became a RS/SS or when combined with the Z28 it became a RS/Z28.
The "Super Sport" (RPO Z27) package was continued. This model offered stylish performance, and was the only way to obtain the 396 Big Block Chevy engine (actually displaced 402 cubic inches).
The "Z28 Special Performance Package" (RPO Z28) was not only positioned as the top Camaro performer, but it put its money where its mouth was. Designed to race in the SCCA Trans Am Series, the 1970 rules changes allowing for the 5.7L engine meant the Camaro was able to now use the 350 engine. The previous Z28's were limited to 302 cubic inches and were known to be tempermental on the street. The bigger engine also allowed an automatic transmission to be used in the Z28 for the 1st time. Due to the solid lifter, high revving cam, Air Conditioning was still not available on the Z28. With a stout drivetrain, including a mandatory 12 bolt rear axle, and a tuned suspension, the Z28 was a match for anything found on the street, or at the track.
While 1970 is the 1st year of the Second Generation Camaro, it is also seen as the last of the high compression, solid-lifter cam, low geared ground pounding muscle cars. While the 1970 Camaro was being introduced, the muscle car market was disappearing, or at least changing. Among the other changes, highlights & distinguishing features for 1970 were....
- Last year for 9+ compression engines
- Only year 12 bolt rearend installed in performance 2nd gens
- Variable ratio steering debut
- Front disc brakes standard
- COPO 9796 3 piece rear spoiler available
- Only year a low-back style seat & headrest offered
- Sunvisor was longer than other models
- Only year a Chrome "C" used on header panel
- Only year a "Camaro by Chevrolet" emblem used on trunk
- Only year side marker lights didn't blink with signals
