Its a lot different since picking up an engine out of a truck is a much different angle than just picking up your dad. try picking him up when he is laying on the floor it will be much closer to that.. I hate to rain on your parade but pulling an engine without an engine pull is going to be a VERY tough task. and even when u do get it out how do you plan on getting the new one in? You should just try and see if you can rent one from somewhere IMO...
