The 1969 model kept the same basic look but with some slight changes such as tail lights and grille, side marker lights, optional bucket seats, and new Road Runner decals. The standard 383ci V8 had 335 horsepower, and was marketed as the “383 Roadrunner” engine, which is also what the air cleaner read. The 383 Roadrunner had 5 more horsepower than the usual 383 Commando or Super Commando, thanks to a more radical cam. In addition to its higher horsepower rating, the 383 also had an astonishing 425 pound-feet of torque, which was the second-largest torque rating offered by Plymouth.
