A good friend of mine had a '74 Hurst olds with the 455. If I remember right, he said it had two Holly Dominator carbs, chrome push rods and all the other goodies, with Mickey T tires (which were wider than me :) He loved going up to mustangs, cameros and showing them what a real car was like. Now it's sitting in his parents yard rusting and falling apart :( Those were the days.
