I assume you're using the MSD tower for the cap. What I did was drill through the center of the cap and removed the conductive nipple. Then, I stacked a bunch of washers up so that the head of the screw sits at about the same spot as the tip of the nipple did. I also had to cut down on the plastic tower to get the post to screw on. Also, are you using an HEI module or did you just run wires from the stock internal coil plug to the coil?

So you're not using an HEI module as well? If not, nothing is sending a trigger signal to the coil. You need to tap into the trigger wire on the distributor plug (the wire closest to the firewall on the 6-wire plug) and run a wire from that to something like a GM HEI module, which is then wired to the ignition coil, in order for it to spark correctly.
