Just spoke with a buddy of mine at GTAuto. He said there may be (not sure yet) materials issue with the carbon electrode in them on the MSD caps; he's experienced the same thing on cars with Accel and MSD/Multiple Spark Discharge combined with high intensity/high voltage type Blaster coils. The theory we have now is once the gap begins between the rotor and the electrode, it starts the arch welding scenario and the degradation gets worse quickly. We agreed on an alternative approach to try. I'm going to try a standard heavy duty Borg Warner cap for Small Block Chevy; brass terminals and 3 year warranty at Kragen. Same Gray color as stock Ford; looks good, so I'll give it a try. We'll see...
