When you do it enough..it's relatively easy. The other night I sat Len's motor and trans into the car in about 20 minutes or less. Car was clean, motor and trans were prepped to go in (at LIM and no accessories). Pushed the car in..brought the motor into the bay and tilted the trans do the ground with the leveler. Down it all went, leveled back out and sat right on the mounts. The longest amount of time is walking around it looking to ensure nothing gets caught or has an issue.
Frequently having a second person like Snowflake who doesn't know the 3800 that well and doesn't know the exact location of each one of my favorite tools will slow me down.
The other night, WOTGTP's car arrived on the flatbed at 6:15pm. At 9:30 when Intrigue98 left all we needed was to fill it up and put the tires on. Max knows the garage and tools well, plus he's worked on a lot of stuff with me and understands the lingo I toss at him. WOT aka Ed, Max and I .. about 3.5 hours on our backs. Kinda funny what I sent them after on the car, some fo the stuff was easy and some was to move out of the way. Had Ed under the car for close to an hour. BTW...I was pretty darn sick and coughing my guts out. No excuses...we zipped it out.
