After having both, I would strongly suggest FI over a carb.
Don't get me wrong, carbs are pretty sweet but nothing compared to the ease of maintanance and performance of FI.

carb is the way to go, it is all inclusive, serves as tb,maf,injectors,tps,iac, etc. etc. no need for laptop, need screwdriver and 20$ box of jets to tune
make all the power u need with a simple powervalve and jetting on the secondaries. works great with a plate under it

Why would you want to step backwards 20 years?
If performance, reliability, and economy were up to par using carbs, we wouldn't have FI today.
It's true a carb is much easier and cheaper to tune up, but FI will be perfect every time once you nail the tune. Weather conditions, altitude, etc all effect carbs heavily, FI not so much. For a street car, you will want the consistent performance and reliability of a FI system.
Ease of install for the carb definitely, but why half-*** it?

Carb. My new build for my pickup will be a carb setup, and it will also be a daily driver. If you know how to tune a carb, or like me and know someone that does!...a carb will be no different, rather more hp. It has been proven many times that carbs make more hp.
The guy that will be building my motor and tuning the carb, just finished building a MILD 455 big block Pontiac for a 69 Firebird. The owner drives it on the street, and gets 13mpg on the highway with a turbo 350. Took it to the track and still managed to pull mid 10's.
I'm mainly going carb just for the simple fact that I know someone that can tune it locally. If I were fuel injected, I would have to drive 7 hours to the nearest tuner.

Carbs are for lawn mowers and weed eaters. I also use them as door stops from time to time.
Assuming you can figure out the harness your self it will cost the same, maybe less to use the FI. Just start a big cammed engine with FI on a cold day and you will know why you should keep the FI. It just runs better. Period. WIth a carb you might get a few more top end HP but the loss of drivability and gas miliage won't be woth the trade off.

just to back up my vote:
i like fuel injection mainly because you can control exactly how much fuel and timing given rpm, throttle input, coolant temperature, etc.
i also like being able to log data so that i'm not as in the dark about how everything is running.
this is coming from a guy who barely knows how to swap an intake manifold on a carburetor equipped car, so be advised that there are countless people who can get better data off a spark plug than i can off a couple of sensors.

well the way i look at it If you dont care about millage and street manors. go carb because your price per HP will be alot less and if you spend the time on the carb the drivabillity can rival FI in a set set of conditions. were the FI accels is if any thing changes like temp, humidity and even barometric press uer. so if its a racer or street pounder go carb to save a few bucks. But if its a cruiser and you want to be able to hop in and get the same performance every time and not have to swap jets go fuel injection.
