I had an Indy intake and Dominator carb under my Shaker. Dropped the K about 5/8", fabbed a drop base into the Shaker base, and eventually made a new air cleaner lid out of fiberglass that almost touched the inside of the Shaker bubble.

With those mods, you could run 'most any intake you want. And set the Shaker bubble height in the hood the way it should be rather than just accept the way it ends up.
