I'm gonna assume that you are spinning the bolt the right way . Lefty loosie, haha.
A high torque 1/2 impact should be able to get it off no problem. The one I use is earthquake brand and is only $90-$100 and is sold by harbor freight. Let the air compressor get up to max (120-130psi) and hit it until you hear the compressor turn back on again. Stop until the compressor shuts off and hit it again. Do this and it should come off after several cycles.
Use a good chrome vanadium deep well metric impact socket too. Put the socked directly on the gun, even a 3" or 6" 1/2 drive extension will considerably lessen the blows of the impact. I also try turning the socket by hand so that the socked is already loaded up against the bolt when the impact hammers deliver their blow.
Use a MAPP or propane torch if you still can't get it off. Hit it with some heat and then hit it with the impact. Rehit it with heat while you are waiting for the compressor charge.
If all else fails, don't feel bad taking it to a shop. I remember the first time I did a Honda timing belt I drove it to the shop and had them pull the bolt off for me.

But it sounds like you already have the motor pretty well locked up.
