There most likely is no provision on the cam or timing cover to accommodate a mechanical fuel pump so you will have to use an electric pump. I took the dribble injection off my '92 van with a 360 because it would intermittenly die whenever it wanted so I pitched the computer, injection and computer ignition and put the "regular" stuff on it. I used the stock in tank pump in my case with a pressure regular to return fuel back to the tank. In your case you will need to add a pump somewhere in the system.
