stalling with AC on, coming off of idle

From what you said in post 5, maybe the compressor is not the problem.
Look under the hood and disconnect the wire that energizes the compressor clutch.
While driving move the selector switch to different positions such as AC, Max AC. Vent, etc.

Will do.

In the meantime, I checked the timing last night. At about 800RPM, with the vacuum advance line removed and plugged, I'm at about 14 degrees. Using a hand vacuum pump, the timing scales up to around 23 with 12 to 15 inches of vacuum applied (and the RPMs jump to roughly 1000, too). At 2300RPM, the timing is close to 35 degrees. Does this seem right?

I'll pull the plugs Friday evening and do a visual. Might as well do a compression check, too, while I have the plugs out.

Could it be that the uneven exhaust sound is due to the RV10/RV15 cam? I didn't think that it had enough overlap to create much of a lope-y sound.
