Last time I had fogotten to put the rotor back under the distributor cap. Make sure your wire lead from the points to the (-) side of coil is not grounding out on the dizzy itself, this also happened to me. It is real easy to do this when you are tightening the leads to the points (one from (-) side coil and one from the condenser in dizzy). Good luck.

Sorry about the Pertronix. That's a fairly familiar story around here now. The few people who've run them without a hitch must be feeling lucky these days!

The Duraspark II conversion is well regarded, and written up here, as a "Sticky". If you want to try it, a lot of people will be able to share their experiences.
