You need to make sure that the polarity of your distributer is correct. MSD has had problems in the past with their distributers being wired backwards. If the phasing is incorrect the spark will fire between the terminal posts. This will chew up the inside of the cap becouse of the excessive voltage required to make the jump.
The easy way to check is to bring your engine up to the timing mark. Probably around 12 degrees BTDC. Remove your distributer cap and see where the rotor is pointing. The rotor should be pointing very close to the terminal it should be firing at. If not you have found your problem and will need to revese the wires on distributer or spark box. You will also need to retime your engine.
Hope this helps.
