Hi Guys,I have a Mopar Performance Electronic Ignition conversion on my '63 Sport Fury 383 with a mechanical voltage regulator.I am being told I need an electronic, "constant voltage" voltage regulator. When I look at places like Mancini, they show these, but they all say "for race only applications."Two questions:1) What is it about these regulators that makes them good for only race applications?2) What is everybody else using?I've had trouble with my "orange" box, and I'm wondering if the voltage regulator is the problem, but I don't want to go from bad to worse.I look forward to your thoughts.Lyle
