pertronix issues

Any time you change any distributor parts (even new points), you must adjust timing. If points, you also had to fool with "dwell". The Pertronix II is similar to GM HEI. To get full benefit, you need an e-core type coil and quality plug wires. If using the old coil and wires, it may be internally arcing at the higher voltage, thus missing spark. To stay factory Mopar, take the coil and plug wires off a Magnum engine (V-6 or V-8). They are all over the junkyards. The Magnum wires appear to be high-quality silicone, with each wire conveniently labeled "coil", "cyl 1", etc, at least the ones I pulled were. Otherwise, spring for MSD or Accel parts, depending on whether you prefer red or yellow and don't mind "Made cheap in China, sold high in U.S.".
