New sheet metal lathed over the existing frame produced a more angular body for the 1970 Chevelle. The most notable change was the introduction of the 454 SS, the most powerful Chevelle ever. Underrated at an astonishing 450hp, the LS6 was one of the fastest cars on the street, and to this day is arguably one of the most collected muscle cars of all time.

The 300 Deluxe was reduced to just two models: the sport coupe and the 4-door sedan. The 1970 300 Deluxe models offered an improved full-coil suspension. Later in the year, an additional option was offered, the Heavy Chevy, served as a base Chevelle with more extensive interior and trim models.

The Malibu shortened its list of models down to four: the sport coupe, convertible, sport sedan, and 4-door sedan. The standard V8 saw a performance upgrade to 200hp with the 307ci.

The SS Packages were now exclusive to the Malibu sports coupe and convertible, as well as the El Camino pickup. Since GM dropped their 400ci limit in time for the 1970 models, Chevy took advantage offering a 454ci producing 360hp, and maxing out at 450hp. The 454ci/450hp Chevelle featured a cowl induction trap door at the base of the hood dome that collected high-pressure air from around the windshield and funneled it into the carburetor for added performance.
