So I'm getting 40 BTDC at 3K rpm vacuum connected, that is correct, no?

You dident post the year, model (country) of your car so I dont know the correct values. If you give me the year and model preferably the engine code I can get you the specs. But every thing sounds about right.
Proceerure is like this
Set static timing key on engine off as spscified usually about 10°
Disconnect vacume check at 1500 and 3000 RPM usually about 27° to 30°.
Connect advance vacume only and recheck at 1500 and 3000 again there should be a gain of about 8° to 12° (total 35° to 42°). Adjust vacume advance to correct. It I recall that is done with springs and shims.
If I recall the idel vacume chack is done with the retard vacume line connected and advance removed. Change of timing from no lines connected is about 5° to 10° retarded.
