There's a thread over on Slantsix.org that used a Buick multi-port injection system for the donor. The beauty of the system is that there are no timing issues. The drawback is that it is not timed to the opening of the valve.
IIRC, the thread also includes a shopping list of what must be culled from the donor vehicle. Obviously the Buick fuel rails won't work, but there are instructions for fabricating one that won't cause self-immolation.
