Bill- You are correct. From my understanding, the objective of the Turkey Pan was to help keep the hot engine air away from the carb. In truth, there really is no "ram air" effect goin on with a turkey pan in a Cobra. I know some people install some rubber weatherstripping around the top of their pan, but it really doesn't form a "seal" around the hood. Fact is, I doubt that much air from the outside gets in thru that tiny little Cobra hood scoop anyway.
The most effective "ram air" setups that I've seen come from a scoop in the REAR of the hood. I owned a 69 Z-28 as well as a 70 Chevelle SS. Both cars had very effective ram air set ups that drew cold air from the rear of the hood off of the windsheild and directly to the carb (that was surrounded by a rubber seal to a hole in the hood).
I've always had the belief that hood scoops that face the front of the car are for directing cooler air THROUGH the engine bay........not directly into the carb (although it passes by the carb on it's way out). The vents on the side of the engine bay (like on Cobra's and Corvettes) help pass the air as well.
Don't know how accurate I am but that has always been my thought on the subject.
