here's a link to CAR and DRIVER's 'Crisis Fighter Pinto' of March, 1974.
They wrapped their 'low' airdam all the way around to the front of the front tires.( at the elevation future rocker panel extensions would pick up, had they chosen to go deeper into drag reduction [ think Pontiac Firebird Trans Am ])
While they were at the nose, they blanked off any superfluous grille opening, and added Plexi headlight bubbles to give some radius.
Under the hood, they went from a 4-bladed cooling fan, to a 2-bladed. A thermostatically-controlled electric cooling fan, pusher, or puller, would be the ticket now. Above 40-mph ram-air essentially takes care of your cooling.
