3 of us were able to move a 1GGZE but that was only 2 litre and pretty much stripped... and there were some pretty stocky guys helping... and i think one of them had to go to the hospital for a crushed toe...
try and borrow an engine crane off someone, or something like that... anything is better then nothing...
in fact, we had a wheeled crane for most of the move... we only had to take it off the car, down the driveway on the crane then into the shed...
i suggest crane... and i also suggest a LOT of flooring in your dads car... like anything solid you can find, for floor and walls... mats, carpets, cardboard boxes, sheets of metal... f**ken anything!
and watch out for leaks...
and good f**ken luck!
