1970 Chevrolet Chevelle

1970 Chevrolet Chevelle SS 454 â?" Frame-Off Restoration by North Georgia Street Rods Why This Car Is Special The 1970 Chevrolet Chevelle SS 454 represents the peak of the American muscle car era, and this particular example makes the case better than most. The 454 cubic inch Turbo-Jet V8 was the largest and most powerful engine Chevrolet offered in the Chevelle that year. That engine, paired with a Muncie 4-speed manual gearbox, put the 1970 Chevelle SS 454 in a class that very few cars of that era could match. To put that in context, 1970 was the last model year before insurance pressure and tightening emissions regulations began forcing automakers to pull back on performance. Chevrolet knew it, and the engineers knew it. The result was a lineup of engines in 1970 that has never been replicated from a factory muscle car standpoint.
