1965 Dart 273 fueling options

Those intakes have been elusive so far.
The Fitech 2BBL EFI supposedly can support up to 400 HP. I don't expect that of course but the idea of having a clean electronic self adjusting tune sounds kewl. I'm hoping to find someone who's run one for first hand experience.
They are not as plug and play as the manufacturers sell you on. I have notice quite a few guys take their FiTech off and put a carb back on. I as well as most of the members here, have ran carbs for a half a century or more with almost no issues. Your choice. You will still need a 4 barrel intake to run one so the search is on regardless.
