Norm Kraus has brought up a new little experiment–or, rather, two experiments.  He and a team of customizers have converted the Challenger into a proper ragtop.  Not only that, they’ve also changed the body to create a “new” ‘Cuda.  Both cars feature the old 426 Hemi V-8, now hooked to a Keene Bell supercharger to put out 725 hp.  The pistol-grip shifter is back, but new-school tech’s been put in with an adjustable suspension.

Aussie artist Michael Leonhard has put out renderings of a Road Runner concept.  The design adopts a theme from the early ‘70s edition of the famed Plymouth coupe.  Envisioned for the concept would be a six-speed manual or automatic, and a choice of three engines: a base 5.7 , a 6.1, and a 7.0 L V-8.  Headlamps only appear when activated from a blacked-out grill.  An illuminated Road Runner label recalls the old image with a modern touch.  A glass roofline is reinforced by aluminum pillars.  The final touch 20″ wheels up front and 22″ out back.
