Get a cherry picker. It will also allow you to move the engine around as needed as you put it into place.
I also used an engine leveler, which made the weight shift a lot easier. In fact, get an air rachet to use with the engine leveler, which is much easier than a manual rachet.

I agree. What is being referred to as rafters in a previous entry, is probably ceiling joists or collar ties. The intent of those items is keep the walls tied together and not (necessarily) to support the concentrated download of an engine suspended from a chain. Your local building department may be willing to share the information from their span tables but saving a hundred dollars for a used cherry picker may not be worth the gamble.
