383 stuttering - solved
Got a new cap and rotor.
The old cap had crappy junk steel terminals and they had white cororrosion all over every terminal.
New cap is "premium" model and has brass terminals.
Should I use dielectric grease on them?
Anyway, she runs freaking awesome again now......smooth as silk
Glad it was simple!

I've heard of using silicone grease on the rubber boots to keep them from sticking like glue to the terminals but not dielectric grease on the contacts. The contacts don't actually "contact". The get extremely close and they arc across. The white you are seeing may simply be from the arcing over time causing oxidation. Rotors and caps are a very common part of a "tune up" on these cars and should be replaced often for reason such as that. Good quality parts such as you are using now should lessen the chance of it happening again too soon and are a good investment in these areas.

I think that using grease on the terminals is just an opportunity for dust and crud to stick to them. Sounds like you are on the right track using premium parts.
If it's an HEI, just a little dielectric grease on both sides of the insulating washer for the coil electrode is recommended.
Glad to hear its fixed!

I won't bother with the grease. I'll just keep an eye on it for a while.
And God yes, it runs sooooo much better! Gonna turn my idle down a little bit - idels a little higher now that it has better spark...
