Hadn't thought about the fuel pump. Can I use the pump from the f/i set up or is the pressure wrong?

How about the manifolds? What years are interchangeable? I'd like to only change the intake if possible, but I'll change both if its better too. Seems I remember my 64 had a heat exchanger kinda set up on it. Basically that 64 had what I'm looking for - a 1 barrel carb with one vacuum line and a manual choke - a near no-fail system.
