I have built and driven both, and both have their plusses and minuses. They are both good. Here are some random thoughts:

Carb:
- Cheap
- Not very accurate, relativley speaking
- Because they are not very accurate, they are easier to tune. Kind of like hitting a target with a shotgun.
- Period correct look.

EFI:
- Kind of expensive. But, you're building a $75,000 car.
- There's a learning curve, and it can be steep.
- A couple of hours on the dyno with a good tuner is only a few hundred dollars, and well worth it.
- Extremley accurate
- Self adjusting for all situations - temperature, humidity, altitude, etc.
- Better gas mileage.
- Smells better
- 8 stack systems on a big race engine can be very complicated. But a Mass-Flo system on a mild small block is plug and play using mostly stock over the counter Ford parts.
- If you do it right, you can easily switch back and forth between gasoline and E85. That's nice when it's really hot.

Having built and used both, I don't think I'll ever go back to a carb. There's just too many advantages to EFI.
