Plymouth Barracuda Hemi (1970/71)
Two of the biggest Chrysler legends from the classic days of muscle car culture are the Barracuda and the 426 Hemi engine. All through the ’60s, those industry icons didn’t mix, at least not in street-legal cars. In 1970, Plymouth offered this legendary engine in Barracuda body style, immediately creating one of the fastest and most desirable muscle cars ever made (via Auto Express).
The mighty Hemi engine was an expensive top-of-the-line option for 1970 and 1971, available in coupe or convertible form. It cost around $900 over the price of the standard Barracuda, and it was installed in just about 600 coupes and only 17 convertibles during a two-year production period. The power was rated at 425 hp, but everybody knew the orange monster delivered more than 500 hp straight from the box.
