Reunited with its original Hemi engine after 52 years, this 1970 Plymouth Road Runner is drop-dead gorgeous and super rare.

The 426 Hemi was first made available on a street ... for compact muscle cars like the 1968 Dodge Dart GTS and 1970 Plymouth ...

It's the same car and the Duster is the original, so it should bring the same number of thumbs up as the Demon. Maybe if Plymouth had made the 440 or 426 Street Hemi available to the Duster it ...

While many remember later iterations of the Plymouth Barracuda ... the most powerful version featured the iconic 455-horsepower 426 Hemi V8.
