The most popular Ford muscle cars are variants of the Ford Mustang produced through its many generations, including the Boss 302 and 429 Mustangs of the early 1970s, the 5.0 Fox-body Mustang of the 1980s and the modern Shelby Cobra GT500. The Ford Gran Torino, Galaxie and Falcon are also popular classic Ford muscle cars built during the 1960s and 1970s, while many enthusiasts consider the Taurus SHO a modern version of Ford's four-door muscle cars.
Though the Ford Mustang was initially conceived and sold as a relatively light and low-powered, two-door sports coupe, the vehicle's lightweight construction inspired the creation of high-powered variants in the vein of Carroll Shelby's original 1965 GT350. Almost all of the muscle car variants of the Mustang have featured V-8 engines of varying sizes, such as the 290 horsepower, 302 cubic-inch engine that gave the original Boss 302 its name. Five-liter engines or 5.0s have become especially associated with the most powerful Mustang variants since the Mustang GT of the 1980s.
Other Ford muscle cars have usually shared high-performance engines with the Mustangs of their era, such as the 1970 Gran Torino King Cobra that featured the 429 cubic-inch engine from the Boss 429. The Taurus SHO or Super-High Output is a notable exception to this rule. The first and second generations of the SHO featured a special Yamaha-built version of the Taurus V-6, while the third generation switched to a V-8 motor and the fourth generation uses a V-6 with twin turbochargers.
