What do you think? Does my Valiant need a Hood Scoop?

Customize your own scoop? The hemi scoop would look sweet if it were downsized, if you were to get a fiberglass one you could cut it up and re-glass it, narrower front to back, side to side, shorter, whatever looks right to you. Fiberglass is easy to work with, just do a little research, and have some acetone on hand.
