So A buddy of mine has a FiTech the basic model 400hp that he ended up not using. thinking of putting it on my Cobra. He has kept the fuel pump on his build so I would need to buy one for this system. The instructions say that I need 60lbs plus and do not need a return although I will plumb it anyway since I have the stock mustang tank that already has it. Question one is Dose the stock 5.0 pump have enough pressure? Summit sells a direct replacement 90 psi for 225 dollars. But when I look at the Ford specs they list theirs in LPH and not PSI. Second question,, I currently am running a Weind Stealth dual plane manifold but I have a new Edelbrock Torker 2 low rise single plane sitting on my shelf,,, Should I do a manifold swap also??? Since I am going efi would I lose drivability with a single plane? From what I understand about the EFI it sounds like it would be good but not sure.. My engine is a stock short block with Aluminum heads and a mild street/strip cam and MSD ignition. I think I'm currently around 350 hp?? Apreciate any feed back thanks.
