I had this same problem and replaced the entire ignition system. Still had the misfire. Then a friend of mine said it could be the alternator. I removed the fan belt and started it up. The misfire was gone. Bought a new alternator and the misfire returned. Ended up being the voltage regulator. Appearently the MSD boxes are very sensitive to voltage spikes, and that was causing my problems.

Good luck.
