Looking for possible carb recommendations...

Hey guys, I just found out that the Thermoquad I was gonna put on my cuda isn't any good. I'm looking to get a new carb but I don't know what I should get.

Can anyone give me some idea as to what would be the best type and what size 4bbl carb for a street driven 68 barracuda with a stock 1977 440, 727 trans, and 8-1/4 rear end (Unsure of the gear ratio). Obviously fuel economy is always a plus, but I would really like something that performs good as well.
