Bob-
I have done it several times. It can be done but it requires some effort. Things that come to mind are: drain oil , disconnect radiator hoses, remove fuel pump stand, generator fan, front motor mounts, jack up the engine 2 inches, and place a 2x4 wood block under the mount platforms, disconnect the tie rod and drag link, disconnect the u-bolts and lift the body up as far as you safely can or remove the front wheels and drop the wishbone down (need clearance of oil pan with the wishbone). I sure others can add to the list.
Everything is pretty straight forward the only problem is removing the front two bolts of the oil pan. Kinda tight to get at them. Finally, rotate the engine until the front crank throw is up. It will take some wiggling to get the pan off.
I know it is a lot of work and others will disagree with me but, I find it better and faster than trying to remove the engine.
