Does anybody know how hard it is, and what it takes, to switch out Fuel injected to a carburated engine? Also whats the difference between port injected and fuel injected and will a port injected be able to install easily in a vehicle that was originally fuel injected? The engine that would be either carburated or port injected would be a ZZ572cu and the fuel injected would be a 5.7L or 350cu. The vehicle would be a 96 Chevy Cheyenne 2500 truck. Yes Its probabley illegal so you dont have to tell me that.

Carbs----spray fuel into the manifold where the gas /air mixes and then goes into the cylinder head where it is combusted. Carbs are like a toilet flushing, not very technical. Fuel injection is calculated by a computer on how much gas is sprayed into the manifold. much more efficient.
Fuel injected vs. port injection not making sense.
port injection vs. TBI throttle body injection
port uses a rail and opens the port for that cylinder when the computer says so.
TBI----was a lame excuse for american car makers to call it fuel injection. they stripped the guts of a carb, and stuck either on or two injectors on top of the carb=we now are fuel injected.
It was proven to be crap and everyone has moved on to port injection.

GM has experimented with Fuel Injection for 50 yrs. The Rochester mechanical version until the "rat" engine, TBI... throttle body injection... which was an attempt to satisfy EPA requirements in a hurry...Corvette called it "Crossfire Injection," and the present TPI or tuned port injection. These versions are described above.
An exchange of any of these with a carburetor would be costly and probably not worth the effort. The manifolds are not interchangeable and probably hard to find unless you have a NASCAR shop in your backyard. Fuel and air supply lines would have to be modified. Programming the computer might be a nightmare. What about emission controls? They would probably have to be changed to pass tests...Would they have to be invented?
Why redesign a motor that has been designed by professionals and has been tested over the years by millions of drivers?
Do you want to install points and a condenser too? What about bias tires?

Johnny666 is exactly right. Also that stock fuel injection off of your small block will not fit a big block. Check out www.summitracing.com for everything you could need to do the job right. Also you can call them at 1-800-230-3030. Good luck.

Going from fuel injection to carburation is like going from power steering to manual steering?

It's not really that hard to switch to fuel injection of any type. The parts are easy to come by, check out summitracing.com or jegs.com.
