Now add a Mercury (Eliminator-style) scoop to her and you're done. Paint it black or body color, it doesn't matter -- it depends on the statement you want to make. The flat surfaces for the scoop mounting studs are already there.
Another (but expen$ive) option is to use a Torino shaker assembly. Those are the ones that are pointed in front, Mustangs are square-front. If you look at the underside of your hood, you'll see that the pointed shape is already there in the reinforcements. It must have been one of those things that the designers considered, but never made it into production.
