I am looking at EFI for a 347 stroker and looking for intake ideas. The new Edelbrock ProXT looks pretty nice, but it is also new and unproven. Any ideas for an EFI induction system? Also, if I do go EFI it will be true multiport injection as opposed to batch fire (triggering groups of four injectors at a time, or worse all at once) or TBI. The aftermarket ECU systems have evolved a lot - FAST, BS3, and others. Looking at multiport, individual injector firing does anyone have experience/recommendations on a computer system? Right now the Big Stuff 3 seems to be the strongest, but I am in a learning mode.
