if set up and operating properly efi is more efficiant than a carb. however efi costs a lot more to fix when it is screwed up. you gotta consider that some people actully do carb to efi swaps. efi gets a bit better gas milage something that is important right now.

Yes, EFI is a good thing. Most importantly, once you get an EFI system going and into good shape, it tends to keep going without much maintenance for a long time, and it doesn't have the drawbacks of carbs...
The best part of all is that most EFI systems are set up so that you can pull codes and it can "tell" you where it "hurts". Try that on a carb.

If the truck came with EFI, you may not be able to get it inspected once you put a carb on it.

what they said.
EFI _is_ a better fuel system than carbs. That is why you don't see carbs on new vehicles.
My suggestion is pickup a clinton's manual for your model year, and pickup a haines manual for 80-96. Combined, they have a boatload of good info.
Pull the codes, and start by posting what you pulled.
Btw, as horton-racing posted, in a lot of states now, if you pull the EFI, you won't be able to be inspected. Don't say you live in arkansas or something where they don't check, because eventually they will. PA never did, now they have an anti-tamping policy.

All of the above answers are true and correct. Particularly the issue that some states do not allow for changing anything that affects emissions. However, to answer your question, yes it is possible to remove the EFI system and replace it with a carburetor.
I personally enjoy tinkering and experimenting with different carburetors and manifold setups. But it is a hobby that may not be right for everybody. If you want the most reliable and economical system, stick with EFI. But, if hot rodding is in your blood and you enjoy tinkering with engines, you’ll probably find fooling around with carburetors a satisfying hobby. On the other hand, there doesn’t appear to be much you can do with an EFI system other that just drive it. Before you remove the EFI system, think about the pros and cons of the issue. Be particularly aware of what your local law allows.
