Carbuerators to Fuel Injection

I've been wanting to get an old muscle car with a Chevy 350 in it and switch it over to fuel injection so that I can afford to use it as a daily driver, and still have some fun. Has anyone ever done this before? I know there are kits for it, but it seems most of the ones i've seen are TBI and are performance, and i'm really looking more for mileage than for power. I'd like multiport, but the only ones i've seen are edelbrock and are about 3000 dollars, a little more than i'd like to spend. If you've done this, what problems, if any did you experience? Besides the basic stuff, what did you have to end up replacing, and how much did the project end up costing in the end? And what kind of mpg and horsepower gain did you experience?

Any help whatsoever on this is appreciated......I just really want a car that looks how cars are supposed to look, has some kick to it, and won't kill me at the pump.

I'm not sure about this but I believe you can swap intakes from a carburated to TBI and possibly others. I would suggest finding a junkyard and get the manifold and computer from an old C/K and bolt it on. I just have never tried it to be sure.

It's not all that easy, you also have to consider what runs that TPI system, a computer, you will have to do all the wiring for that as well:alien2:
