Understanding Ignition Dwell – Pertronix
To understand ignition dwell, we first need to review the operation of the ignition coil. It may seem like magic to have 12 volts from the battery go into the coil only to have it output a spark with at least 15,000 volts, but it is all physics and principles of electricity. Inside every coil there are two sets of windings surrounding an iron core.

Ignition Dwell
My experience is if you have a weak battery it causes weak ignition and your motor is down on power. If you have fouled or worn out plug you have weak ignition and are down on power. I know from my experience with two stock motors that they really really lost power with old plugs. The oil mix just killed the ignition and killed the HP.

Single coil dwell and spark duration settings.
Spark duration should be called "minimum spark duration". All free time is spent in "spark" (i.e. coil discharged). For this 6-cylinder engine you need 3 sparks per rev. If you go with the typical defaults of 3ms dwell, 1ms spark duration, that's 4ms total per spark. 12ms per rev works out at 5000rpm. So anything up to 5000, there's room.
