Engine install from below?

I had the engine and transmission mounted on casters so I could roll them around as a unit. Starter, water pump, fan, headers, alternator, etc. are all bolted on and torqued in place. I also installed the fan belt, starter cable, etc. so I wouldn't have to deal with that stuff later on.
I lifted up the front of the car and rolled the engine+trans into place then lowered the front of the car back down on to jack stands. Then I pulled the engine and trans up into the car and bolted it home.
