Howdy BA M:
More information would be helpful to give you a meaningful suggestion. Are you looking for a 1 barrel bolt-on replacement? Or something that requires modification and/or adaptations? There are reasonable options in either case.
Another consideration is what distributor you have on your engine? Early 200s have a carb-distributor combo that are somewhat dependent on each other. Changing one will compromise the function of the other.
Depending on your circumstances and goals, a distributor upgrade might be worth considering.
Also, let me suggest that you create a logical, sequential plan so that what you do with this birthday money can be complimented by your next purchase and you end up with a complimenting package. With bolt-ons that would include, 1 improved exhaust, 2 improved distributor, 3 improved carburetion.
Don't forget safety issues as you go along too.
How about some more info on your car and your longterm goals for it.
Adios, David
