Well....
I checked with Bruce at F&B and the throttle bodies are a good bit shorter than the carburetors.
2⅜" from plate that tops the intake to the top of the TB:

I could save 1" if Bruce fabbed a top plate to replace the Weiand top, but that would take a LOT of plenum volume out, but let's just go with that for now.
Have to have an air filter, so the factory element is 2"+2⅜" for the throttle bodies, let's call that 4½" and subtract the inch saved by replacing the top plate of the intake, and add ¼" for the replacement plate. That is 3¾"....
If I cut out the hood bracing so the skin of the hood was all that was there, I would have 3¾" of space. That is just cutting it too close! Even if I get an inch of extra space by using a 1¼" K-member spacer to lift the body relative to the frame, that would be taken up by the top and bottom air filter element base and cover. SO CLOSE, but I think that the smartest way to achieve the Weiand and the Air Grabber air door/scoop is to just get the space I need with a glass hood and a raised power bulge.
