Engine trans.swap

[Peter J]

Hey Guys,
This winter I plan to swap out my engine/trans with the ones I rebuilt this summer. My question is: Should I pull both engine/trans. as a unit or engine then trans.? I have a stationary eye hook (ceiling) and a chain fall rather than a mobile engine hoist. Also replacment the same way? I plan on doing the work myself.
Thanks for your thoughts and advice,
Pete
