I've got a Ford DURASPARK II adapted to mine.
The stator/reluctor detector parts inside the dizzy literally never fail (mine spent 165,000 miles in an F-150 before I put it in the Bird).
The controller units are available anywhere anytime - cheap.
The controller unit is divorced from the dizzy - so you can hide it in an easily serviced location. Plug in connection takes seconds.
Controller has a starting retard built right in (-6°) when you connect the white trigger wire to the starter solenoid.
Power transistor will handle a coil with 1.2 OHMs internal resistance and no ballast resistor.
Can be built with all Ford parts.
Also can use the Ford detector directly with an MSD red box and MSD patch cord. Or...............
Can operate with Ford detector and GM style 4-pin modules (that have extended dwell as RPM increases).
