Four guys to lift, one to raise the jackstands and shit would be the minimum to such a heavy body if you want to pull it off in one lift. Jacking and blocking it gradually can be done by yourself but it takes time and you must be very careful not to tip your body over.
I once did it this way. Jack one corner up, then I nailed some blocks of wood together, and raised another corner, then I put the floorjack on some blocks and raised again until I got it high enough to roll the frame off under it. It almost took the whole day so getting some friends together and buying a lot of beer for them would be faster.
