My first mopar "stranded" moment with the HEI setup

There seems to be a lot of problems with the HEI. I just drove Route 66 to Santa Monica Ca from Battle Creek MI with a 65 Barracuda slant six with a Chrysler electronic distributor and a MSD Street Fire box. We ended up driving 5889 miles and had the center electrode in the distributor cap started to crumble at about 3000 miles. I changed it in San Bernadino and drove it back to Michigan.
The friend that went with us had a 65 Dart slant six with HEI. He had ECU trouble all the way to California and back, changing multiple ECUs.
I think I'll keep the MSD.
