LA 360 Engine refresh?

I saw a video on that a while back... They used a floor jack slightly raised to support the weight of engine/ K-frame assembly, unbolted everything and removed all the lines that were connected and dropped it on dollies, then jacked the car up with a cherry picker. Seems easier to manage alone, rather than trying to guide it in from above. I need to do my homework on that one though... It seems simple in theory, but I’m sure there’s pitfalls waiting for me.
