Hey PR - I have already had the show poodle crowd tell me this Road Runner I have appears to be worthless unless (they hate the 508 six pack) I restore it to stock 400 engine etc etc.....
The one thing I kept thinking about this week is the marriage of a Coyote drive train with the Road Runner.....that with a Borgeson steering box and removing that heavy air grabber hood in favor of a fiberglass one.
How much weight would that take out of the Runner? 300# with the engine alone, 50# minimum for the hood and I think the borgeson box is 15# lighter. Ditch the battery to the trunk, removing the trans cooler and lines(stick shifted now)
Think of that cutting 400# off the nose of this car pretty easily with some elbow grease but achievable.
