For street use prior to full restoration, I'm installing a ProComp HEI dist on the '69 350/300hp. In reading up on it, I've come across a couple of concerns maybe you can provide some insight on:
First, I've heard that there might be issues with the "mechanical" voltage regulator in running one of these affecting the distributor module, and possibly causing early failure if it's not a quality module. Any experience with that, or recommendations?
Also, should I run a hotter spark plug? Currently running the equivalent of a AC R-44.
