Hyper-Pak–Equipped 1970 Plymouth Duster

About

This 1970 Plymouth Duster is said to have had its 225ci inline-six modified in the 1970s with numerous performance parts from Mopar such as a Hyper-Pak intake manifold, a four-barrel carburetor, a high-compression cylinder head, electronic ignition, tubular headers, and a dual exhaust system. A manually shifted TorqueFlite automatic transmission, an 8¾” rear end, and 4.88:1 gears also were featured decades ago.
