This subject has been beat to death on this forum, check the archives. Here are a few things to consider:

1. In some states, conversion to carbs will make it impossible to pass smog on the visual inspection. Even if carbs are permitted visually, you may have trouble passing smog as carbs produce higher emissions.
2. Conversion to carbs on a stock motor will not produce more HP and will adversely affect starting, driveability, performance, and emissions.
3. The cost of a complete carb conversion (carbs, manifolds, linkage bar, fuel pump, fittings, etc.) usually costs more than fixing problems on the FI system.
4. Cars with carb conversions usually sell for less than those with properly-operating FI systems.

On the positive side for carbs, if you're building a big-bore engine and want a high-lift, high-duration cam (not desireable for street use, IMO), carbs are the way to go. Or if you want to build a high-boost turbo or supercharged engine. Jack Raby uses carb on his big bore engines and the feedback is very positive. Personally, I used to have a 2.2L motor with carbs - it worked OK at best in comparison with properly operating D-Jet.
