In my decidedly biased opinion, SEFI is the best possible method of fuel management. The first one I remember working on was the Buick 3.0 Liter V6 in the mid-1980's, when everybody else was using a very primitive throttle body setup. The advantage to a sequential system is that it fires the injectors one at a time like an ignition distributor, a fraction of a second before the intake valve opens. Since the injector nozzle is aimed into the port pointing right at the valve, a cloud of vaporizing fuel hits the tulip area of the valve just as it's opening. All the fuel intended for that cylinder gets into the right place, not some random volume of poorly-vaporized gas that's floating around in the manifold. SEFI produces more uniform power, and better fuel economy than either carburetion or TBI injection. The trick would be writing a specific programming sequence for the stovebolt engines. The problem that comes to mind right away is the siamesed intake port configuration, but since the firing order separates the cylinders for the shared ports by several positions, that can probably be dealt with adequately.
