With Pertronix per say. Ignition Wires must be Suppressor type, the Correct Coil must used for the version, and bypassed ballast. Also the plugs should be gapped a bit wider, but if the previous is correct it may be a little experiment for the final plug gaping. I have the III with the correct III coil and Taylor suppressor wires. Resistor is bypassed from behind and really is a good set-up. Rev limiter included on the III. I can tell you, My Taylor Solid core wires used with a Gold Box from Chrysler were of no use, as I thought it would not matter. Sparks were flying everywhere on initial start. I used Pertronix so I could hide it all for a factory look and succeeded! Best I have used yet. Chrysler, MSD, Mallory all left me wanting better.
Read up on the manufacturer recommendations and follow them religiously for the Ignition system you end up using!
