The second-generation Chevrolet Camaro was produced by Chevrolet from 1970 through the 1981 model years. It was introduced in the spring of 1970 Build information for model 123-12487 was released to the assembly plants in February of that same year. It was longer, lower, and wider than the first generation Camaro. A convertible body-type was no longer available. GM engineers have said the second generation is much more of "A Driver's Car" than its predecessor.
Dubbed "Super Hugger", the second-generation Camaro was developed without the rush of the first generation and benefited from a greater budget justified by the success of the first generation. Although it was an all-new car, the basic mechanical layout of the new Camaro was familiar, engineered much like its predecessor with a unibody structure utilizing a front subframe, A-arm and coil spring front suspension, and rear leaf springs. The chassis and suspension of the second generation were greatly refined in both performance and comfort; base models offered significant advances in sound-proofing, ride isolation, and road-holding. Extensive experience Chevrolet engineers had gained racing the first-generation led directly to advances in second-generation Camaro steering, braking, and balance. Although it began its run with a number of high-performance configurations, as the 1970s progressed, the Camaro grew less powerful, succumbing, like many production cars of the era, to the pressures of tightening emissions regulations and a fuel crisis. Major styling changes were made in 1974 and 1978; 1981 was the final model year for the second-generation Camaro.
Most of the engine and drivetrain components were carried over from 1969, with the exception of the 230 cu in (3.8 L) six-cylinder — the base engine was now the 250 cu in (4.1 L) six, rated at 155 hp (116 kW). The 1970 Camaro SS 396 had the 396 cu in (6.5 L) L78 rated at 350 hp (261 kW). Starting in 1970, the big block V8s (nominally 396 cu in (6.5 L)) actually displaced 402 cu in (6.6 L), yet Chevrolet chose to retain the 396 badges. Two 454 cu in (7.4 L) engines (the LS6 and LS7) were listed on early specification sheets and in some sales brochures but never made it into production. Besides the base model, buyers could select the Rally Sport option with a distinctive nose and bumper, a Super Sport package, and the Z-28 Special Performance Package (priced at US$572.95) featuring a new high-performance LT-1 360 hp (268 kW) 380 lb·ft (520 N·m) of torque 350 cu in (5.7 L) V8. The LT-1, an engine built from the ground up using premium parts and components, was a much better performer overall than the previous 302 cu in (4.9 L) V8s used in 1967-69 Z-28s; greater torque and less-radical cam, coupled with the 780 cfm Holley four-barrel, permitted the Z-28 to be available with the 3-speed Turbo Hydramatic 400 automatic transmission as an option to the four-speed manual for the first time. The LT-1 engine in the 1970 Camaro Z-28 came from the Corvette.
