The 1970 Chevrolet Chevelle SS 454 LS6 was a beast, plain and simple. The 450 horsepower assigned to this Chevelle V-8 is the highest power rating ever given to a car from the original muscle car era, according to Brauer.
The high rating, however, was an understatement. "Even this rating was below the engine's actual horsepower, which was likely somewhere between 470 and 500 horsepower," he said. This Chevelle's current market value is $75,000.
