I'd find a Clifford 4 barrel intake manifold with an Edelbrock carb, would help a lot. It may need some taller gears to get down the highway, or not depending where you live. Check out Patrick's Antique Autos and get a catalog, has lots of good info in addition to their parts. And stay right here for lots of good advise.
