    I think it would be cool, but I like carbs.

    you need a standalone ignition system like the MSD. its not cheap but it works.

    i'd say that it will run better and cost less to go with the stock efi setup.

    carb direction costs more money then it does using the EFI route.

    there isnt one advantage for going carb with what youre wanting to do. Youll probably lose power to be honest

    it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference

    MSD kit with intake= $750


    I want to do this myself. Keep it old school with new technology.

    Power should stay the same, maybe more. That carb is gonna flow more CFM.

    Go for it. Unless I beat you to it!

    The carb will flow more CFM and make SLIGHTLY more power.
