Myself I would go with a holley(quick fuel has a good rep to my knowledge) based carb but I lean more to performance.For bolt on and go nothing wrong with an edelbrock 600cfm with electric choke.An edelbrock performer(or similar low rise dual plane) is fine.

Anything you buy may need some adjustment/fine tuning to run its best.

If you are buying all from one place summit is as good as any.Make sure you make a list and go over it twice for all the little stuff you may need.

You may need a longer throttle cable or different kickdown rod for the four barrel also.Unless you switch to the adjustable cable from Bouchillon performance.
