Re: 91 Chevy 350. Keep efi/ throttle body vs. carb

running? keep it for sure

if not running, you might spend a little on parts to fix it, usually need a fuel pump and injectors and TBI rebuild kit which is just a bunch of gaskets.

1991 TBI harness is pretty well standalone, lots of info on the web for hooking it up in a chassis. you will need an electric pump capable of about 12 psi

keeping the 4l60 (the 91 is not an "e", you are right) will give you overdrive, which is the benefit over a TH350. I am guessing you have a divorced transfer case, make sure the extra length of the 4l60 will fit.
