will Air gap RPM manifold fit ???

When I measured my 69 Barracuda I had a little over an inch to spare from the top of the air cleaner to the hood running the Eddy performer and Eddy carb. I put the Air Gap and the performer side by side and the Air gap is 1 inch taller. So simply put a large ball of Play Do (like I did) on top of your air cleaner and close the hood (carefully) then see how tall the Play Do comes out after closing the hood on it. You didn't say what kind of intake (or air cleaner) or carb spacer you're running??
