I used to run a Trans Am shaker scoop off to the side of the hood (people thought,, "what the f#*@!" Your hood scoop is not in the center. Ha! I thought it was cool.
Anyways, cold air feeding the carb from the shaker scoop sealed to the hood , (no under hood heat would feed the carb) intake sitting over the headers = hot intake manifold, even in the winter here.
