Petronix Electronic Ignition Any Good?

Replies are about different Pertronix. The original Ignitor keeps the ballast resistor, so has no dwell control, similar to the original Mopar ECU. Ignitor II uses no ballast, so more like the first GM HEI. Ignitor III adds MSD and rev limiter ($$). Some answered about Pertronix custom distributor ($$$).

Many here use the GM 8-pin HEI (1985-95 V-8) with its coil and connecting cable. TrailBeast here used to sell kits w/ new parts. An easy junkyard pick. I have one in my 3 old Mopars (225, 273, 383). I carry a spare module ($20). The original GM 4-pin HEI is more custom wiring and less reliable connections.

I recall the original Ignitor in the early 1990's J.C. Whitney catalog, or at least one which looked the same. Another points distributor retrofit was Crane Cams XR700 (began as Lucas). I installed one in my 1969 Dart slant and 1965 Newport. It has a plastic optical pickup wheel (several for different engines). I had both an optical pickup fail and later the control box. Fortunately had a spare box in the trunk to drive home.
