The small, two-door, high displacement engine powered muscle cars have long remained the classics on the American roads and in the auto industry. They have made heads turn with their roaring engines and looks. Here is a list of America’s top ten classic muscle cars picked because of their popularity among passionate car lovers as well as their demand at used car auctions and dealerships across the country.

• The 1967 Pontiac GTO:

Back in 1964, by fitting a V8 engine of 389 cubic inches into a Pontiac Tempest, the Pontiac engineers defied the informal ban that General Motors had against putting any engine larger than 330 cubic inches in a small car. A good number of car lovers claim that the 1967 Pontiac GTO is the car that gave birth to the muscle car segment.

1968 Plymouth Road Runner Hemi: The Road Runner is considered to be a definitive muscle car because this explosive vehicle is capable of delivering raw power and torque. This legendary car is equipped with a 425-hp, and 426 cubic inch V8 Hemi engine, making it ideal for drag racing.

The 1969 Chevrolet Camaro ZL1: With just 70 units of this car built, this rare bird is much wanted by car auctioneers, collectors, and dealers across the world. It was originally equipped with a 427 horsepower iron block, which is the most powerful engine ever built by Chevrolet. It is on our list of the top ten American muscle cars for this reason. It is one of the rarest Chevrolet cars produced till date.

1969 Ford Mustang Boss 429: One can think of Ford Mustangs as a brand of muscle cars by itself. It has been ruling the roads for half a century. The 429 cubic inches, 375 horsepower V8 engine equipped Boss 429, is one of the rarest models for car collectors as Ford produced just 1400 units.

1970 Buick GSX Stage 1: Although Buick was late in entering the muscle car market, the GSX package has been one of the best in its era. With just 687 GSX units built, 488 units were sold in stage 1, and the car was given some tuning later on, which gave it some real power.

The 1970 Plymouth Hemi Barracuda: Offered in two engine choices of six and eight cylinders, the “Cuda” is considered as the top muscle car of all times. Revving up 425 horsepower, the Cuda was tailored for high acceleration as well as superior suspension.
