Hi There,
I have a Chinese made fold up engine hoist that I got from Big Lots many years ago, the lower legs flip up for storage and it has a three or four position extendable mast with the longest setting rated at 500 lb, I've changed a lot of engines with it, you have to be somewhat careful of the footing as it can be a bit unstable if you yank on it too much but that being said I've changed engines in both my Malibus several times in a two car garage during Winter with the door closed from the side, over the fender as you describe, I always do just engine or just transmission as I don't like the extreme angles that one will encounter trying to change the engine/trans as a complete unit, anyway I'll generally have the car up on stands in the front high enough so I can get underneath a bit and then will pin the transmission to the floor with a jack so it doesn't move about and is at an angle that will line up with the engine easily, I'll get a couple say 3/8x6" bolts and cut the heads off of them and screw them into the lowest bell housing bolt holes for line up pins, hang the engine at a similar angle to how the transmission is sitting in the car, I've used both chain slings and hoist plates that bolt to the carb flange on the intake manifold, put the engine over the fender into the engine bay and line it up and secure it to the transmission, pull the jack out from under the transmission and then let the engine hoist down, it may take a little finagling but it should drop right on to the mounts, Both of mine are standard trans so I also have the clutch to deal with, Automatics are that much easier, It will also make life much easier if you hammer the pinch weld flange where the floor meets the firewall flat while the engine is out, I've done that to both mine, it gives you much better access to the bell housing bolts, as I say I've done it that way many times and it works the same way every time, Hope it helps!! Good Luck, Have Fun!!! KillerDave
P.S. You might check and see if your transmission mount is intact, a broken mount will give you a bunch of headaches trying to line up an engine!!!!! Later
