A 4" drop is probaly gonna make for a major air flow restriction.. How much distance between the base & the lid at the pinch point?? Not much I'll bet...




Exactly. After 2 or so inches of drop, it really does not matter. It really becomes a question of carb to hood clearance and the narrowest restriction between the carb and A/C lid. Increasing the drop will just allows a taller element.
