OEM intake manifold?

Hey Guys, Can anyone tell me if a Mopar CASTING NUMBER, 1851898 intake would be any good to put on my 1968 Newport 383? One thing I would like to do before spring is to swap the 2bbl for a good 4bbl setup.I really don't have the money to spend on new stuff.What would be a good used carb to fit on this stock car?Are the old Carter AFB's any good or should I look for a used Holley?Also, what about a Carter Thermoquad #6-2472....there is one on Ebay for $50?
