Not done it myself but a competent mechanic I know (who had never done a V8 Jag before) took 2 days. He had a 2 post lift and transmission jacks. He never mentioned any specific problems other than getting exhaust apart, just said it was tedious with a lot of bits to loosen / undo. I don't know if he removed exhaust to lower back of engine or if leaving it in place prevented gearbox or propshaft being removed.
