I run the Hemi 472 single carb in a 64 Savoy. Very Streetable. Full TTI exhaust has a nice sound to it. Started with 3.91's and ended up with 2.94's to make it cruise better. Can drive it anywhere.As mild as my Slant Six car till you mash the pedal.Yes you will never get it to hook on street tires but who cares??? AND top end?? you will run out of road way before the engine runs out.........
