I like the idea of a staged carburetor on a small cube engine. In other words, one that has a primary barrel(s) and a secondary barrel(s) and opens them progressively.
If sticking with a two barrel, a Weber would be a good choice. For a four barrel, a small Edelbrock AVS would be good.
Either way, upgrades to the intake and exhaust will be necessary to take advantage of any improvement.
A good, high flowing intake manifold and a good free flowing header and larger than stock exhaust will be mandatory.
Otherwise, you're pissin in a fan.
