I have recently used a Pertronix distributor, a full MSD system, and the new Progression Ignition distributor. They are all good, but my favorite by far is Progression Ignition. It is self contained and you set its curve (both mechanical and vacuum) on your phone. Also stores multiple curves and has a rev limiter, easy starting via advance retard, anti-theft mode, and various gauges (speedometer, tach, vacuum, and real time advance) that display on your phone. It is easy to setup and use. All for $529.
