This could be caused by reversed polarity to your dist. One way to see how bad rotor phasing is, look on the bottom side of your dist cap; if what I call the burn mark on all eight lugs is way off to one side? The burn mark in all 8 lugs should be somewhat centered. If not; then you have possible reversed polarity or just a screwed up dist with really bad rotor phasing. Of course check your reluctor gap. Set at .08-.10 Also possible bad coil.
