msd dizzy problems
I have an MSD pro billet dizzy(mechanical advance) on my 390. Since I've put it on I've had problems with corrosion on the inside of cap. i have drilled the holes msd suggested as well as runnning another ground wire. Is there anybody else who has had this problem?

Yup. I've had the same problems. I switched to their vented cap and it seemed to help. I have not looked inside the cap since switching but the moisture related failures stopped.
I noticed burn marks or shorts in the cap material between posts. If you reused the cap and simply drilled some vents, you probably still have the shorts. I'd sugges getting a new vented cap and a new rotor.
