6. Chevrolet El Camino SS 454
The Chevrolet El Camino was conceived as a half-car/half-truck vehicle for carrying light loads, delivery duty and useful tool for small business owners. And most of them lived their lives exactly like that. But, 1970, Chevrolet introduced the wildest El Camino of all in form of El Camino SS 454.
The mighty 454 V8 LS6 was a 7.4-liter Chevrolet`s big block engine with 450 hp official rating. The engine delivered around 500 hp in real life and it was a fire-breathing beast and one of the best engines of the muscle car era. In the El Camino SS, this engine provided significant performance figures which were close to the best regular muscle cars of the day.
