Hello. I'm in the middle of an install on Holley dual sync distributor to replace my GM HEI distributor on 350 Chevy. I just noticed that I don't have a coil for the dual sync distributor. What coil should I use without any ignition boxes like MSD, etc.? I had only a GM HEI and it worked fine with it.
Second problem: I bought new battery with double posts as recommended in instructions. Battery cables in the big posts, and Sniper connected to the smaller posts. When I remove negative cable (car side), I still see 8 volts in the cigarette lighter? Car is stock 1972 Corvette. Is this okay?
