If you have a non A/C car you have two sources for fresh air, the kick panels and ball vents. The kick panels have a slide on the panel that operates a damper door. The pull under the dash operates the ball vent damper; it's way up under the dash, and ducted to the ball vent.
Secret Ram Air... that's original FireBenz.
Thats on 68's-n-9's. 67's had the 250 RA.
In other words, 250 RA was forced through the cockpit via vents in the door glass,forcing additional thrust on the gas pedal via the drivers foot.
