I bought a flat hood from AAR and had to cut a hole in it for the dual quads. I called AAR since I would have been cutting thru the bracing/structure. They instructed me to buy a celotex styrofoam insulation sheet. Following their instructions I cut some strips and placed them on the underside of the hood. I completly glassed them over and all was good. The hood was structurally sound and my carbs and air cleaners were poking thru. (Added a scoop later)

I was told the foam is just the form/mold and that the cured fiberglass is the where the strength lies.

I dont agree, its really not a bad hood as it sits, I'd have no problem using it as is, once all the zdus btackets are in place it would sit nice and straight. I just want to beef it up a bit to make it stronger and as far as the corners go, if there easy enough to fix, I'll fix em, if not its no big deal.
For some of us, working on our projects is the best part of having one. I enjoy working on them even more then driving them, I'm usually looking for something to work on or modify.So somthing like this I look foward to.

Very true ....foam offers ZIP in strength ....BUT IF you put some mag, alum or lite-weight steel tubing in there ... the hood is almost as stiff as a steel hood.
I have done this on at least a 100 hoods.

Don't question the Doc. Well at least not on Fiberglass. He is offering a very sensible and practical fix. Sure you can stiffen it with a top-hat of glass on a core of anything, but the conduit is easy to work with and will add additional stiffness.

Hey Doc, any tips on adding material to the edge, as is the case in my corners. Should I just use a flat surface butted up to the topside of the hood and overlay a few layers of mat from the underside to build it up?
Gonna build my wood stand tomorrow fitted to the stock hood so I can lay the fiberglass hood down and start working on it.

, but then thats all it's supposed to offer, the increase/added stiffness is not the foam itself, its the increase in the depth of the cross section ( it could almost even be just air , except that is hard to form)that one is trying achieve. Steel ubing mightwork well and easy, but hard to imagine it outperforms foam lb for lb. 
Most definately.
