Did I slip a tooth?

From your haphazard explantation it could be BAD PICKUP in the distributor or reluctor gap adjustment

You need to tell us SPECIFICALLY wire by wire what you did and what the symptoms are............

Did this distributor you are now trying to use EVER work that you know of? If not.........it's suspect......

WHY did you change the distributor..............?

Is the MSD new? Have you been running it? ????
