drunken idle

My idle wanders up then steadies, then wanders down for no obvious reasons and repeats. Will do this 2-3 times in a 5 minute period.
76 with rebuilt 350 (5K), turbo 350, new edelbrok carb and intake- 2101/ 1406 w elec choke. New MSD streetfire ignition w vac advance. 22hg vaccum at intake at idle and steady needle.

Is my vac advance messed up?
Could my fuel pressure be too high?
Do I have a vacum leak?
Timing chain already worn after 5K?

Thanks in advance for any suggestions.
