Are you serious? I don't know where you live and what the laws are, but if I were to leave my car "abandoned" on a street where I don't live - it would be towed off or stripped down and hauled off for junk before the week was out.
Are you doing the engine rebuild? If not, what about storing it at the shop that is doing the rebuild? If it is a nice old car, it sort of acts like good advertising for them to have it in their yard.
Otherwise, pay for the tow and the storage building.
