Feels like it's running on 5 cylinders as it has no power at all. Now I'm worried that I could have screwed it up more driving about 4 miles. My first step is too pull all the plugs and go from there.
Is it normal too have transmission whine (especially in 2nd)?
I guess I'm just very paranoid right now worrying that I'll screw things up. Should I wait until it stone cold before pulling the plugs?
I'm a BMW guy and I'm trying to learn the in's and out's of this thing.

Firstly, sorry for your loss. Lousy way to acquire a great car.
I've never driven a 3.0 930, but they're lower compression (6.5:1) and smaller displacement, with the same truck turbo as the 3.3.
It has to be even worse off-boost than the 3.3. And must feel peakier than heck in-boost.
Gearboxes can certainly provide the auditory sensation that large amounts of metal are turning around in there, even if they're in good shape. The harder the tranny mounts are, the more pronounced this seems to be.
I'd say check the obvious things (like all the exhaust headers get hot, oil clean, level good, no split or popped hoses etc), drive it for 10-12 miles until the oil is good and hot, make sure the brakes are good, don't stick/pull, tires inflated etc. Normal stuff for a car sitting all winter.
It should run much better when it's up to temperature. Which takes a good 10 minutes driving around here. 4 miles for me this morning (Eastside) was half-warm, barely off the cold enrichment.
(Each oil change leaves 1-2 quarts in the system, but typically you drop/replace 10 quarts. That's a lot of oil.)
Then find a suitable place, make sure ALL the round things are pointing dead straight ahead and nail it. You knew the '77 has chocolate brakes, right?
Trust me, you'll know if it's boosting...
