This would be an interesting video. I'm sure many on here would like to see how the distributors compare to each other. I understand you are a busy man but hopefully you can find the time to do this. Keep up the the good work.I can test ALL these distributors as stand alone parts. And what I’m telling you is that IF the distributor has SOME retard it’s far enough up the RPM scale that most guys would never need to account for it.
