OK here is one of your few conundrums with that. First you want to see if the intake gaskets are the same from one engine to the other. If it is then you can swap. I know you wont be able to put the carb where the throttle body is. They just don't bolt up.
Now if the intake manifold gasket is not the same then you will have to change the head from the older engine to the newer engine. Ford 300 6cylinder engine had the same scenario. to go carb the head had to be changed to complement the carb

A previous person wrote, if you really want to do this swap it may require changing everything from the cylinder head up. If you are lucky maybe the intake manifold up. Another thing to think about is fuel pressure. Depending on the type of fuel injection, the fuel pump on an injected vehicle will supply 14 to 45 PSI. Carburetors require 7 PSI. If you feed this much pressure to a carburetor you will flood the engine with fuel and quite possibly burn your car to the ground. You will need to either change over some of the fuel system or install a pressure regulator to drop the pressure before the carb.
To agree with another writer, It should not cost $600 to repair your car. If you are willing to go to the effort to make the carb swap you should be able to fix the problem for less. Further, there are a number of reasons the automakers all changed from Carb's to EFI. Fuel economy, driveability, emmissions, and reliability are all much better with fuel injection in my opinion.
Good luck! Rusty

you are looking at more than 600 to convert it to a carburetor, and you will find yourself with a mega headache. you dont need a new "efi" there are many components that make up the efi, and you should fix whatever is causing the problem. if you like causing yourself pain, i recommend hitting your hand with a hammer.

Injectors inject through head into cylinders, you would need to replace whole top of motor down to block.
