1970 Chevrolet Chevelle SS 454
Many consider 1970 to be the apex of the muscle-car era, and the Chevelle SS 454 is a weighty piece of evidence for that argument. Chevrolet offered 2 versions of the 454-cubic-inch V-8. The LS5 generated a very impressive 360 horsepower, while the LS6 punched out a whopping 450 ponies. It's the LS6 version, with its Holley 4-barrel carburetor, that put the SS 454 on this list. No other muscle car would equal the horsepower wallop of the 1970 SS 454, according to HowThingsWork.com. It was the last great gasp of the muscle-car era.
Not only could the SS 454 blow the doors off most of its competitors, it looked good doing it. Chevelle's swept-back roof line provided the illusion of speed, even when idle. A bulged hood was part of the design, alerting passers-by that something really special was happening under it.
