Terry Krystofak posted pictures of his 67 GT500 here. I saved them but am having difficulty finding them right now. There are several pictures of the engine compartment.
Personally, I'd weight the results of those pics heavily...whenever I can find them.
As far as other very similar 2x4 Ford intake configurations mentioned, why would they be irrelevant to this discussion?
As in other discussions that involve Ford assembly plant procedures with other components, why would we consider them to not be consistent? I'm not suggesting that there would be any consistent logic of a Ford assembly plant, Heaven forbid, but that logic has been used before and accepted?
