Jhonboy086ERCONVERT

Im swapping out a Factory 4.0 V6 from my 08 Pony to a '94 281 4 Valve its got the teskid block and everything of course, and have some questions, im getting all stuff required together before I ever pull a bolt. So far I have the Fresh built 4V, a Cobra Upper and Lower intake, found me some cobra exhaust cams, and an 8.8 rear end im planning on 3.73's. Trans at this point is just a T45(Temporary) still thinking about what exhaust, Long tubes most likely, and I have a Ron Francis conversion harness on order now for the swap. My questions are what do I need for ignition for the swap? Also what do I need to make to the fuel system work? Ive think the 6er is factory returnless fuel system not completely sure tho im assuming fuel pump, rail, injectors. and lines?
