1971 Plymouth Barracuda 426 Hemi
The Plymouth Barracuda was the first pony car, which they introduced two weeks before the Ford Mustang. But despite its cool design and features, it was always in the shadows of the Mustang and Camaro. However, in 1970, a totally redesigned model arrived with the Dodge Challenger which Plymouth built using the same platform and engines. As with Dodge, the most powerful versions were the 440 Magnum with a 395 HP and a Hhemi 426, delivering 425 HP.
Most experts agree the Hemi engine produced a lot of advertised power. However, the real output was closer to 500 HP than to the declared 425 HP. But this engine option was quite expensive, costing about a third of the price of the car itself. That is why only a small number of Hemiemi-equipped Barracudas left the factory in 1970 and 1971. Most of its buyers were serious street racers who wanted one of the fastest muscle cars Plymouth ever built.
The Hemi 426 in the Plymouth Barracuda could sprint from 0 to 60 mph in just 5.4 seconds. Interestingly, magazine testers back in the day said people could its performance with just a few simple modifications to the intake, ignition and carburetor jets. So, those tuned Barracudas could go even faster.
