Todd,
sometimes a fresh set of eyes and troubleshooting procedures helps. I may be wrong, but I recall discussions from another thread where several provided pointers. After verifying the basics, did you have your MSD box/distributor tested, correctly? I did not see a response on that. Sometimes the smallest things can be overlooked when it becomes frustrating; and it happens to all of us. It sounds like it's time to get a professional with a new perspective on it. Good troublehooters can usually sort it out in less than one hours shop time. Good Luck!
