Petronix Electronic Ignition Any Good?

Pertronix has a good reputation. If you've got it, and the car's not showing signs of ignition problems that would require a different setup, might as well save the money and effort for where it's needed.

The orange box has been junk for years and years. Whatever box colour, the Mopar electronic ignition, while better than points, is easily outdone by other ignition systems (HEI, for example). And the distributor in the MP kit comes with an advance "curve" totally unsuitable for use on the street (two ultra-lightweight springs: all the advance dumps in all at once).
