Yeah, out the bottom engine, gearbox, sub frame drive shafts and front suspension struts all complete on both cars.
Make sure you get both cars high enough at the front, take measurements from the bottom of the brake discs to the top suspension mounts so you know you have enough room to pull from the bottom and out the front with the front bumper removed... Place the engine, box etc on a home made cradle (pallet is good) with trolley wheels at 4 corners... Getting the rear ends of the car on ramps helps level the body out and eases the angle that a crane has to work at so the whole cradle doesn't drop and swing into the bulk head and damage it.
Plenty of trolley jack's and an engine crane helps to support the weight of the front unit and lets you control the decent easily. repeat on the donor car. Then you now have both units on the deck and free to remove any bits and swap over without having to worry about limited space... Cam belts are a lot easier to do as is water pumps, starter motors, manifolds and clutches , anti roll bar bushes etc.
Rebuild the cradle back up as an all in one unit drag it back under in position and slowly lift with the engine crane back into position connecting lines and cables as they come into position then aligning the top turrets and mounts, then bolt the sub frame into position.
Personally, I would take the time to include any jobs that need doing on a regular basis like bushes, arms, clutches cam belts etc. While off the car so it then becomes a worth while investment and gives peace of mind knowing it has all been done
If in doubt, label every pipe and electrical connection as you remove them and label groups of bolts and nuts and put them in food bags. Before you know it, you will have performed a complete overhaul and the car will need for nothing for three years or so... The pride factor and knowledge that it has been done properly is priceless
