The First 1967 383 A-Body, 'Barracuda or Mr. Norms's Dart'

Rhinodart nailed my comment. 65Val, Dodge and Plymouth divisions operated separately back then.Plymouth came up with the Road Runner concept first. Dodge passed,until they saw the Road Runner sales. Straight from Mr Norm on the 383 swap,and the Road Runner concept guy. Mopar Action,interviewed both.
