Dont this several times recently and come tell you that the only way i would ever dont it is by removing the prop whole before moving the engine.
If you undo the rear the prop will hit the floor and you will struggle (if at all) to get the engine out with that jammed omn the floor. Remove it at the front and you will struggle to release it from the flywheel bolts on the rear of the engine because you cant move it back. Release it in the middle and it hangs there locked against the front studs and in the way!!!
Lastly break it under the car and you have to mark it and line it back up later to balance.
20 mins for the prop if theres two of you OR hours of fustrated work only to remove it anyway.
Thats my opinion and the way i do it,hope it helps.
