Which dropped base air cleaner fits?

I actually have a new in the box 14" x 4" K&N filter element. I just looked and with the 750 HP on an air gap intake and a I" phenolic spacer. My Hood clearance is nothing. My 68 Barracuda has a fiberglass w/ Hemi scoop hood on it, but the hole hasn't been cut in the hood yet. I'm thinking I'm going to have to have the hole cut in it no matter what housing I use.
