Opinion on Electronic ignition for 68 340

It all depends on what your used to working with and are comfortable with. They all have their pluses and minuses. I use a stock electronic distributor and keep a spare ECU and ballast in the car. I've only ever had 1 ECU go out on me, an Orange box that lasted about 4 years. If you go electric use clean wires and good grounds. The ECU box case must be grounded.
