    If I am not mistaken you;ll have to change the wiring harness to start with as all the plugs are different for the efi system the EFI itself should bolt right in

    Dont know why it wouldn't work,

    You would need at least:
    ECM
    Harness
    Sensors,
    new intake manifold
    new injectors
    new throttle body
    lots of misc parts and gaskets.

    The Harness would be best bought new from HD they are not that expensive and would have all the RK connectors in the correct position.

    Other than that you could put the dyna harness on the frame and check to be sure you have all the stuff.

    I could be wrong but I think there might be a difference in the fuel line fittings from the gas tanks. Check that out too.
