To switch to fuel injection you need to replace everything. The computer, all the related wiring, fuel pump and lines, intake, throttle body, mass air if equiped, coolant temp sensor and related sensors. and distributor. If you feel comfortable doing all of this it can work. Oh and you will need the schematic for vacuum lines and wiring diagram to help. It can be easier to turbo a fuelie if it is not a speed density system, mass air type usually take to mods better. But if your looking for more power you could try a cam, four barrel manifold and headers. Should get you around 100 more horses, possibly as miuch as 150.

You don't have to replace the intake manifold to switch to fuel injected. You do have to make provisions for injectors on the manifold though.
I was thinking about this and the easiest way to go appears to be an Electromotive TEC3 system.

You could also try one of the Holley TBI systems. The originals that came out 10-15 years ago sucked, but the new digital units work very well. Since they are TB you only need about 8-10psi fuel pressure so fuel system modifications usually are minor.

I saw once where a fellow took the grand national turbo and efi system and put it on a chevy 292 straight six that was in a 37 chevy coupe all steel that run 10.13 in the quarter, keep in mind everthing was highly modifed and still very streetable, it would actually be no different doing that to a ford 300. No one likes the tunability of the ford speed density however if you where to have the injectors installed into say a carbed intake and fab up a throttle body/adapter, and had a dyno for endless tuning then it would work. How about a dual carb intake that has two 4.9 throttle bodies one on each flange (with an adapter), and twin turbos one for each. Tell me that wouldn't be cool.
While none of that would be unrealistic it would cost ya, everyone has a point the tbi units today work really well and all in all are fairly cheap going to a efi setup. Try turbocity.com I believe they have tbi systems and if you haven't already look at turbonetics. Good luck with the project

The only real advantage to switching to fuel injection would be fuel economy and tunability. If you're just looking to throw on a turbo, you can do that without fuel injection. But if you drive it every day, you should be able to get a fairly substantial increase in fuel economy by switching to fuel injection and therefore it might be worth it to you. But for me, it'll be easier and cheaper to just stick with carburation.
In my opinion, if you're going to go to all the trouble of fuel injection, you might as well do it right. Get a system designed to add fuel injection to your motor and give you the ability to program it specifically for your engine, rather than ripping off some system from a car because the engine is "similar" to yours.
