Waitaminte, Hold the phone. What are you talking about, 12 volts? I have a 1968 Chevy C-10 pick up truck with a 327. It ofcourse had a point distributor. I replaced it with HEI, the kind with a coil mouted on top. And the wire I used to connect to the HEI is the same one that was on the old dis. Are you saying that this wire is worng to use? That it may be to weak? And what would that resister look like? This is an issue I never have thought about. Thanks, John.
