    Big Bore Ignition Suggestions

    I'm about to start wiring a newly built 750 big bore engine and I'm looking for suggestions on which ignition to run. The stator is factory so it will probably need to be upgraded also. Since this is a frame-up build, I am starting fresh. So... what ignition unit should I put in this thing?
