There is an ad in one of the Mopar magazines that state they are selling 4-barrel intake manifolds for the 6.1 Hemi. So if you want to go old school it can be done. It's possible that this Challenger has one of these setups.........but why would you want to go with a carb?
(Sorry but the color does nothing at all for me...BUT, if the owner likes it that's all that matters).
