Thread: Holley EFI & Ford TFI

  1. #1

    Default Holley EFI & Ford TFI

    Hello, I have a Ford 351W EFI 1996. I installed a stroker and camshaft and it's very difficult to control with stock ECM. So I'm thinking about use a Holley HP EFI for it. I've already installed them in three Chevy engines running more than 700 HP, so I like it and know it very well.

    The problem or question I have is the following: The engine has a REMOTE TFI MODULE. It will work or I need a distributor with the module on it, and I have to use the gray or the black module? Regards.

    Holley EFI claims the Ford TFI is only compatible with module on the distributor. I'm not convinced, but I don't use Ford TFI so I can't test that theory.

    Thanks Danny. So my best option is to use a dual sync distributor for 351W? Holley or MSD (MSD is a little cheaper than Holley, is there any difference? Regards.

    Yes, or install Coil-On-Plug ignition.

    If using Holley's 556-112 CNP coils, the Holley 558-318 CNP coil sub-harness is also required (or the Holley 556-128 CNP Big Wire V8 Kit).
    For LSx coils, Holley 558-307 CNP main harness plugs into two GM 12579355 CNP sub-harnesses or Holley 558-321 LSx coil sub-harnesses.
    If you had a Holley EFI LSx main harness, you wouldn't need the Holley 558-307 CNP main harness or the 558-318 CNP coil sub-harness.

    Either one of those Hall-Effect crank & cam sensor distributors will work great with Holley EFI.
    I like the MSD red cap & wire retainer and longer harness (it also states a sealed ball bearing).

    When I first installed my HP, I used the stock distributor remote mount TFI, gray module, on my Lightning. No issues with it, worked fine, was at about the 700HP level then.

    My Holley 351W Dual Sync Distributor came with a black MSD cap & wire retainer. Based on the Holley marketing video, both MSD and Holley are made in El Paso and I'm going to assume they are essentially the same part other than the color of the cap.

    Thanks, that's what I want to do, but looking the dual sync distributor price, I thinks it's a good option too, and that way I'll have all new.

    Thanks for info, that's what I'm thinking.

    They're not exactly the same distributor. Read post #6.
