    Depends on the 200 shot...but 36 pounders might not be big enough.

    agreed. I have a friend with a h/c combo and 13:1, we are looking closer to 46lbers

    he does have a sick motor I just don't want to see you pay good money and end up with injectors that are too small and still maxing out on your setup
    do a search for I think its (morton) they have a good web site and there is also (bosch) either should beable to set you up with the right size

    if you get close without the juice you can always go with a wet system for the track

    Ford SVO 42# injectors (green top) should work well for you. They're cheap in the aftermarket, and can be found used off late model Lightnings.

    The computer will spray what is needed based on the injector tables and tune.

    Best to be close though.

    Fix them? I don't know... they aren't really broken to begin with.

    They are a direct replacement.
