Ah yes, the early years....with electricity!!!!
What I do not understand in George's post, was how the two system supposedly differ in terms of the voltage "firing"?
The pickup in the distributor is the same. The method to make the unit "fire" is the same. Line up the rotor vane with the pickup coil, and tap distributor with a screwdriver handle....spark happens. Now, how would a module make this different??? Coils are the same or darn similar....
I think either system you choose needs to be treated with respect.....less you want the wife to see you out dancing around your car waving your numb fingers in the air.....
