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 absolute peak of the muscle car era. It was the year GM lifted its internal displacement limit on mid-size cars, which allowed Chevrolet to stuff its biggest big block â?" the 454 cubic inch Turbo-Jet V8 â?" into the Chevelle's engine bay for the first time. The top version of that engine, the LS6, was factory rated at 450 horsepower and is widely regarded as the most powerful production V8 General Motors ever put in a passenger car during the classic muscle car period. This is that car. The VIN on this Chevelle confirms it left the factory as a genuine SS 454 with the 450-horsepower Turbo-Jet big block â?" not a base 396 with SS trim bolted on later, and not a clone.
