Pontiac chooses to call it a working Ram Air system but how effective it is at ramming air can be debated.

Exactly. I feel that this thread has been dancing around the topic of ram air effect a little too much given the OP is only asking about cold air induction. As has been pointed out, they are two separate functions.

Since OP is only asking about lowering the air inlet temps on his '67 GTO, opening up the stock hood and using factory-degined "ram air" parts should be sufficient, easy to accomplish, and aesthetically pleasing as you say. No need to go off the deep end if all you're concerned with is pulling in cooler air from outside the engine bay.
