i have just finished up the hardware and efi mods for this conversion. iwould like some feed back on what I have done . the engine is a stockish 289 rebuilt recently. the fuel inj. system is from a 1996 f150 5.0l truck. as you will see I have built a new upper plenum with reduced volume and shorter overall runner lenght to help with the early style cam. The injector firing order has been changed and this system only runs 1 hego (o2) sensor. My concerns are the egr system and vss and whether someone could possibly check my wiring diagram and pin-out for possible problems
