The 1967-1971 Plymouth GTX was Plymouth's muscle car warrior. Introduced in 1967, the well-equipped Belvedere boasted plenty of cubes with the 440 Super Commando V-8 and a mighty 426 Hemi.

For the 15 years between 1955 and 1970, Plymouth did mean Performance -- and the capital "P" is intentional. The first Plymouth V-8 arrived for 1955; one year later, a modified version powered the hot, limited-edition Fury.

Exterior styling of the 1967 Plymouth GTX was surprisingly muted, though what was under the hood wasn't. See more classic car pictures.

In the Sixties, Plymouth launched the Barracuda, which eventually mounted a small challenge to Ford's Mustang in the ponycar field; resurrected the famed Hemi V-8, which was simply unchallenged for street performance; and scored big with the Road Runner, America's first "budget" muscle car.

For 1970, Plymouth unleashed the Superbird, a wildly winged Road Runner designed mainly for stock-car racing.

And there's another point: From 1959 through 1972, Plymouth was among the top four makes in the manufacturer point standings in the National Association for Stock Car Auto Racing (NASCAR). In 1971, the Superbird gave Plymouth the NASCAR championship, winning 21 of 38 Grand Nationals.

Many street Plymouths in these years could be equally impressive. Off the showroom floor, for relatively little money, you could choose from a whole fleet of hot performers, from nimble Formula S Barracudas to burly bucket-seat, big-inch Sport Furys.

Yet all this had developed very quickly. Don MacDonald, in his test of the new-for-1967 GTX, recalled that only a dozen years earlier, Ford had been the only low-priced car with a V-8: "Plymouth has come a long way from the days when the three sails from the Pilgrim-carrying Mayflower were the symbol of its power and speed."

On the next page, we look at the Plymouth GTX's engine and design.
