What air cleaners to clear hood

Steven190 · Apr 30, 2019

I am trying to plan ahead some and wondering what type of air cleaners that everyone is using on the following combination.
Air gap manifold
holly 4150 style carb.
Want to clear the hood.

now I am using a 14" X 3' flat base lid. The carb mounting and the filter bottom are the same height.
How much of a dropped base to use? It looks like the Air Gap is about a 1/2" higher manifold that the RPM manifold.

Order a GM #6422188 air cleaner base. It was used on high performance Chevrolet cars with Holley carb. If they need to know application, just tell them 1970 Corvette with LT1 350 and they should have no problem finding it.

I had one on a 440 in '67 Barracuda with Holley SD intake, 850 Holley carb, 14 x 4 air cleaner under a flat hood. Even had room for a nitrous plate with no problem.
