Arguably the most iconic Mopar muscle car of all time, the E-Body-based Barracuda was the basis for some of Plymouth's most outrageous performance vehicles including the 340-cubic-inch AAR designed to take on the Trans Am series and 426 Hemi models designed to dominate at the drag strip. If you have more modern designs for your E-Body, our Gen III Hemi Swap systems will give it a modern heart while retaining its Hemi legacy.
