Quality comes to mind. Did you read the link from the prior post to yours Oldsalt?
Nope. However, If quality of components is an issue, then quality of results should also be an issue.
Changeing the points will surely affect dwell unless the rub blocks [and some other geometry] are identical. So it is certain that the 'normal' point opening used with the RE points would have to be altered to accomodate.
I was pointing out that the coils, HD and RE, are different. VW or a Chevy 6 ignition coils are also different. It is not easy. unless a person is really into radio theory, to calculate resonate circuit voltages. But it is certain that useing a condensor optimal for a six cylinder engine coil, or a double wound secondary HD coil, will require a leap of faith that the permeability of the coil's iron core, inductance of the coil, the reactive inductance, reactive capacitance, and resultant resonate frequency are the same as the RE coil. I'm betting against it. Therefore my money would be on a condensor, regardless of its preceived quality, that was selected by engineers to do service with a particular coil for an engine operating in a particular RPM range. The strength of the spark at the plug can be significanly degraded by the use of a inappropriate condensor uf rating.
Condensors rarely go bad. I wonder how many Vince has replaced, because they TESTED bad? I'm thinking it would be about the same number as the sets of RE points that went bad.
