i have my stock throttle body injected 5.2l 318 and was wondering if my other 85 318 carbureted will hookup and what kind of modifications im looking at here? any help is really appreciated

 

Why do you want to remove the fuel injection?

You should also search on this as it has been discussed numerous times...

There is alot to consider when you go about replacing it with a carb:
Are you going to use the electric pump - if so you need to do a some rewiring and install a regulator. If you go mechanical you will need to pull of the timing cover and install an ecentric on the cam and make the lines, and remove the pump from the tank.
You will need to work on the ignition system (Dist and box and wiring)
You will need to work on the charging system (wire in a regulator)
If you have AC or Cruise, you can get the AC to work but forget the cruise
