1970 Plymouth Road Runner
With fresh new styling and a Air Grabber hood, the Road Runner was one heck of a muscle car.

1970 Plymouth Road Runner

The 1970 Plymouth Road Runner received fresh new styling on the front and rear and a new Air Grabber Hood was added to the list of options which consisted of a under mounted dash switch that opens a power operated trap door on the hood, revealing a shark cartoon with the words "Air Grabber". Under the hood, engines were basically unchanged, although the 426 Hemi engine went from solid to hydraulic lifters in the interest of greater durability and cleaner emissions, and the Road Runner's standard four-speed manual moved to the options list, replaced by a heavy-duty three-speed.
