I would probably look into some type of aftermarket fuel injection system before I would drop that kind of money. At least you wouldn't have to adjust the carbs every now and then and get all the benefits of modern day EFI.
agreed. it is not a lot of fun making adjustments on those, there is not much room. I used to have to remove the center carb to make internal changes, other than float setting.
that said, they do look cool, and can work well, with some tweaking.
that particular manifold really has some limited value, because it is an "after"-aftermarket one: mopar performance, not original style; so aar and T/A restorers would be disinclined to buy it for the finishing touch on a big bucks restoration.
