Good morning gentleman. I'm wiring up my 40 and I'm trying to decide how to finish my ignition system. I currently have an electronic 2 wire distributor that is said to be stand alone and no ignition box is required for it to run. Most wire diagrams show an ignition module in the equation. I originally was going to run without one since the distributor would run without it. Now I'm contemplating using a gm hei ignition module. I don't want to run a msd 6al as I've had too many failures of them and they're not cheap. The chrysler modules seem pretty prone to failure as well. What are your thoughts?
