I'm pretty sure this topic has been discussed before.  Is it possible to use a duel quad manifold on a street Y block with modern carbs?  Will it fit under the hood of a 1955 Thunderbird?   I realize the carbs would have to be small and they won't be all that efficient, but they sure would look great on cruise night. A friend did this back in the day with WCFB carbs.  I imagine I would have to build adapters.  Anyone ever tried this?  How drive able is it?
