1970 PLYMOUTH DUSTER INTRO YEAR
Introductory year for the car Plymouth built to compete with the Ford Maverick and Chevy Nova. Spun off the Valiant platform, and sharing sheetmetal from the cowl forward, they did what they could to end the similarities there, however a “Valiant” emblem appeared above the “Duster” badge on the front fender of the 1970 (only, all later years are devoid of the Valiant name). The new Duster was supposed to be fun and exciting, and sporty. In fact, the Duster came as a 2-door coupe only. While it shared its door skins with the lowly Valiant, the rest of the Duster’s exterior was totally unique, with a semi-fastback roofline. For the 1970 model year, they came in two basic flavors: the basic Duster and the performance-oriented Duster 340.
1970 PLYMOUTH DUSTER ENGINE OPTIONS
Base Dusters came standard with the 198ci slant-six, with the 225ci slant-six optional. The V8 options consisted of the 318 LA-series small block V8, and the 340, also an LA-series small block. Of course, the Duster 340s all came exclusively with the 340 engine.
