Questions about electronic vs HEI

Actually, there is a significant difference in the burn process versus spark energy and number of sparks per spark cycle. Even for one spark, the shock wave initiated by a higher energy spark is greater and creates a larger 'spark kernel', which spreads the flame faster through the burn process.

No, I did not just make this up.... although it may sound like it LOL! This type of knowledge has been around for decades, and is well documented in literature. Here is one such article: google "combustion flame velocity versus spark energy" and download the .pdf paper that shows up like this partial link:

Start looking at pages 32-41... it takes some mental digestion, but the conclusions are there. Multi-spark discharge and HEI ignition systems have been out there since the 70's for a good reason.
