If you like things simple and want to spend the money, the Davis Unified Ignition (DUI) replaces the coil, igniter and distributor with a 2 wire hook up (one to 12v and one to the tach)and a single vacuum line to the carb (or none if you choose the mechanical advance model. Hedman headers are available without the O2 port as well.
