I used a cherry picker with a harness I bought to do corvettes years ago:
The harness was cheap, that crew was out of Texas Motor Speedway...very pricey!
I don't know for sure, but I would guess the tub is around 250 - 300 pounds. Someone else may know exactly. Two guys could probably carry it, but I would want more to lift it up over the engine when removing or installing. There is to much fragile stuff to clear...and I think only 2 guys would have trouble.
When I originally popped the tub off I was scared to death, having read the restoration book, that it was so weak it would break in half. I had it braced and triangulated, and the whole works. As I worked with it more, I realized it is really pretty sturdy. If the parts are sound, and you show respect, it will be fine without the elaborate bracing. I would not, however, chance throwing it on a trailer and drive around with it.
The dolly in the picture was great for the blasting and working on the sills, etc. It was easy to roll around solo, and I placed the wheels inboard far enough that the whole thing could be tipped on its side and would stay there while I welded...or did whatever.
