Experiencing a problem where car wont pull over about 5500rpm. Lays over and starts busting up, lol. 7al2 box, took out rpm chip, no help. New cap rotor and pickup but didnt see anything wrong with any of it. Msd dist is not locked out. Goes to 38 degrees by 2500. Its not fuel or carb. Tried different carbs to no avail. Think I have a ignition box issue. Big question is if I get a new one I want to be able to use it with a holley fuel injection system. Recommendations?
