Dave,
Make sure that you have voltage going into the coil. A quick easy check after that is to just take a stock coil and put it in and see if the car fires. I switched from Holly coils years ago because they kept going bad. They are most likely a lot better now but I use a Jacobs on all of my cars now. If your distributor has the optical sensor that is very likely the place to look as they will blow quite easily. If you have the inductive distributor like the one I have then it probably isn't the distributor, but you can't count anything out for certain. So try the coil first as they are cheap compared to ignition modules. I keep an old coilin my tool box for just this reason. Only takes a second to hook it up and if I still have trouble then I know which way to go.
