I don't think that will work as it is without a drop base air cleaner of some sort. Ive seen talk on this site about good drop base setups. My 71 440 Challenger has an RT hood. It has a stock 4 barrel intake and a vacuum secondary Holley 750. The wing nut gets just barely into the hood if I don't use a real short one or take material off. I have a 3 inch " normal height " air cleaner. I think the RPM intake is a little higher than my intake. We'll probably both end up with a drop base type. Good luck !
