Correct. The scoop is down in the "boundary layer" of airflow and is too low for any ram effect. It functions merely as a cold air intake (which is worth about .2 of a sec reduction in ET on our car).

Compare that to the Firebird Formula hood, which would be a much better design.

But the Formula hood scoops would look really funny on a 65 to 67 GTO. I'd lean towards the 71/72 GTO's intakes grafted to the 65/66/67 hood up front for real RAM Air. Kinda like what Shelby did going from the 65/66/67 hood to the 68 RAM Air hood scoops up front on the GT 500. That's where it did trick for the full RAM Air effect.

I agree that the ram air effect is minimal on the '65 through '67 gtos. The real difference is in the air temperature that makes for a denser charge. By and large, under-hood air is quite a bit hotter than outside the hood air. The larger the difference between the two, the greater the difference in performance with the ram air pan. I am proud to run one of the estimated 300 original ram air pans on my '66. I don't know how great of a performance difference it makes, but it is a part of history. It looks cool too! Jerry.
