Throttle body to carburetor ??s

You maybe able to run a regulator and get the fuel pressure down enough for a carb but you will have to come up with an ignition system. The PCM controlled the spark / timing advance. Plus you have to run some type of relay to power the fuel pump. The PCM only closed the ASD relay after it saw a signal from the ignition. That way the fuel pump only ran when the engine was running. I suppose you could power the ASD relay from the ignition switch key on. Been a long time sense I've worked on a TB vehicle.
