    MSD box PN 8168,8158 with automan kit and MSD trim to suit harness to the box.
    The units are very dependible but only as good as the upstream equipment that control it when the timing is changed. The tiny crimp electrical fittings on the pressure switches can break off if not properly installed/maintained on the MSD harness. Never failed us that we know of.
