Here's the set up I presently use with a four lope cam. It's a Chevy distributor turned down to fit an 8BA wired with a conventional coil. Originally I ran points wired in series with a condenser as Bubba mentioned. I have since converted over to electronic ignition. The cam is covered up by the magnet and the rotor is removed for the picture.
So you can use ether coil, it just maters which way you wire the points.
