1973 Plymouth Road Runner

Other Years:

General Overview

The 1973 Road Runner received completely new sheet metal and had more conventional squared-up front-end styling, which resembled the four-door models and actually increased sales by 40%.

Quarter-mile times were in the 16s and top speed dropped to barely over 120 mph. This was the beginning of the end for the Road Runner’s muscle car status.

The new standard engine was downgraded to Chrysler’s workhorse, the 318ci V8, but it was equipped with dual exhausts and bumped power up to 170 hp.

No 440ci cars with 4-speed manual were built. The 400 was the biggest engine Plymouth offered with the 4-speed, which could also be had with the 318, 340 (1973), and 360 (1974) engines. The 440 was still available, but with the TorqueFlite.
