Thanks so far!

Other than the heat/weight issues, was the cast iron+quadrajet setup negligibly "worse" than the aluminum+holley setup? I would think the open element air cleaner would be better than the closed, chrome version...?

I would speculate that the Q-jet / Iron Intake / Open Element might actually have a slight edge. More carb CFM, Higher Air Cleaner CFM, and I would <span style="font-style: italic">suspect</span> that the Iron intake isn't far behind the aluminum intake in terms of flow capacity. Those "square corner" winters intakes weren't very good, compared to the 302/LT1 manifold or any modern aluminum intake.
