I'll eat my shorts if the chassis is over 1000lbs. I would say in the area of 500lbs. I have moved this thing onto a dolly and back and forth onto the rotisserie several times. I know I can pick up both ends and with my back I shouldn't be (I should say lifting). I have needed to shift it around a few times and have a pretty good idea of the weight. The front is not too bad but the back is much tougher. The MGB was around 300 and 2 guys can carry that frame with no problem. 3 guys could carry the Pantera without too much problem; 2 in the back and one in the front.
Here is the dolly and rotisserie build:
http://www.rc-tech.net/pantera1/roto/roto.htmThat page shows how to get the height pretty close for a Pantera. Each is different as to the dirt, filler, paint and will change as you work on it. I was originally off a little. With a scale and a real simple weight and balance calculation will show you how much you need to move the balance.
As I did body work it also changes. I added a screw in pipe base for dumb bells to alter the pivot. The chassis would spin freely and stop at any point.
The construction time of the entire roto was a couple hours:
You cans the dumb bells in the next photo:
