Got everything worked out.
1. installed new Flame Thrower coil -- did not fix anything
2. installed new Ignitor -- Smoothed out at higer RPM. Still idled like a dragster.
3. Found bad positive wire to the alternator -- did not fix the idle but corrected the charging problem.
4. I noticed a three port vacuum source that had one open port. I thought i recalled a plug on it but it was missing. I also noticed a empty port on the A/C canister so i ran a line from the empty port to the canister. This was the idleing problem. i removed the line i installed and capped it. Idles smooth as butter again. I must have knocked the plug off while removing and installing the distributor.

I think a number of problems came up at the same time.

Next in line is to figure out what is going on with the vacuum canister and why the PO has the heater core by passed. I smell a problem here.

Thanks for the help.
