Better Performance Output

Are you suggesting cutting my hood to add a taller Air filter element and inducing cold air through an aftermarket hood scoop?

I ment just to rig up a (underhood) cold air intake system. Add some large diameter tubing front the radiator support to the carb.
Cutting the hood is an option ofcourse if you like to go that route.
Cold/cool air always makes more power. Just look at what modern cars have for intake systems.
