The Plymouth Roadrunner was a muscle car produced by the Plymouth division of Chrysler Corporation from 1968 to 1980. It was available with a variety of different engines, including the 383 and 440 V8s.

The 383 V8 engine was a powerful and reliable option, producing 335 horsepower and 425 lb-ft of torque. It was capable of propelling the Roadrunner to impressive speeds and providing strong acceleration.

The 440 V8 engine was even more powerful, producing 375 horsepower and 480 lb-ft of torque. It was known for its high-performance capabilities and was a popular choice for muscle car enthusiasts.

Both the 383 and 440 V8 engines were strong performers, but the 440 was generally considered the more powerful and high-performance option. It is difficult to say which one is definitively “better,” as it ultimately depends on the specific needs and preferences of the driver.

In the video below you can see a very nice Plymouth Roadrunner in two engine types, 383 and 440.

Same car one year later with a 440 engine. Both times accelerated from a standing start without high revs.

Both are absolutely beautiful sounding engines but people of course have their preferences! Watch and hear and tell us what’s your favorite? //Youtube/Willy Coyote
