Fiberglass hood mods... crazy?
I think you are over-thinking it and may not even pass tech if they see the cut hood. I have two thoughts.. first... seal the carb to the hood with a scoop. If you need to engineer a pan to run an air cleaner but it is worth power and ET. Also, what blown said... Instead of cutting anf adding weight and hardware to make this flappy thing... Just use some radiator or heater hose to raise the rear edge of the hood 1". When you're done racing... pull it out and the hood fits normal.
