1974

The most successful sales year for the Duster. Unfortunately, this would also be the year that the 340 V8 was dropped and replaced by the 360 V8. Despite the greater displacement, decent 245 bhp rating and greater torque, the heavier 360 engine couldn't match the outright performance of the old 340.
