Hey, nice find!
One would guess that if Ford had actually done more than wind tunnel testing, some info on its race track performance would have shown up. Back then, I do remember Ford and Chrysler (Dodge/Plymouth) crowing that the Talladega Torino was xxx faster than the standard car and Dodge doing the same for the winged birds they developed. Would be cool to get one in race shape to see what it could have done but nah!
Way too valuable to do something that dumb!
