8. Plymouth Hemi Cuda
Two of the biggest Chrysler legends from the classic days of the muscle car culture are the Barracuda and the 426 Hemi engine. In 1970 Plymouth offered this legendary engine in the Barracuda body, immediately creating one of the fastest, most desirable muscle cars ever (via AutoExpress).
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. They installed it in about 600 coupes and only 17 convertibles during its two-year production period. The power was rated at 425 HP but was rumored to have delivered more than 500.
