Sadly what's left of that is an utter shed.
Might well be an original ac schnizer car but if every panel on it is fucked, no gearbox no diff no sears, and a knackered engine it'll take a comfortable 10k to get it even vaguely presentable again. My engine rebuild from spinning a bearing is looking to run to approx 7k, so rebuilding that with a new block is going to be likely more, then seats, gearbox, diff, interior/dash, and unit.....!
Best thing to do would be to break it. There's few k in the engine top end if it is a csl top end, and stuff like the alloys and bonnet and carbon fibre door trims etc.!
