Is the OEM ignition system from Chrysler has good as MSD and other ignition system sold today?
Will conversion to electronic ignition buy you anything? If you are talking pure performance, nothing whatsoever. The rule of thumb: if there is no misfiring now, you can swap to an ‘arc welder’ ignition system and gain nothing.
The gains from breakerless systems are mostly related to maintenance reduction (down to near zero) and timing accuracy and consistency. Breaker point systems start deteriorating from day one.
The ’72-up Chrysler EM electronic systems were good, although the mag trigger design was not quite as consistent, or as good in low temperatures, as later Hall-effect triggers.
