318 EFI and carb

What year did Dodge stop using carburetors on 318s and switch to EFI? Can the later EFI engine be converted to carburetor by swapping the intake from the earlier 318? I need an easy fix for a smoking 1974 Duster.

They started using TBI in '88, and that lasted until '91) when they introduced the Magnum series with MPI.
To run a carb on the TBI motors, you need to swap the manifold, carb, throttle cable and linkages; and the distributor.
