A miss is usually ignition related.
I'd start by bypassing the msd.
Stock distributer?
Stock coil?
Original TFI?
Change the wires?

What rpm is it doing it and what are you doing when it does it, as in are you cruising, hammer down, coasting, downshifting etc.

If the car has a 6AL on it then this is a pretty simple fix. Disconnect the MSD box and take it to your work bench. Open up the box So you can see the wiring on the inside. Put the box back together and immediately smash it with a large hammer.
