HEI ignition module

Yes, I 'pick' at things that are incorrect.
Oh, & I understand the concept...& far better than you do.
Of course long coil + & - wires will degrade spark performance, but it is a matter of degree. By making the wires a couple of feet longer so that the coil &/or ECU can be more conveniently mounted, the 'loss' of spark energy would be minimal & unlikely to be seen on anything but laboratory grade equipment...if seen at all.

The 5-6' of wire was your quote & I never proposed a mounting position that would require that length of coil wires. You mentioned inductance, but left out capacitance. If the wires were separated slightly, there would be NO inductance.
