WOW! Did you cut or modify the firewall on this? I have been thinking of putting a 383 in my 66 Valiant. I have to say I never even thought of using the Max Wedge manifolds, but it looks awesome! And they are available now for less than a pair of Dougs headers... Also what type of mounts are you using or are you going to just use elephant ears?
