You can easily remove the engine with a normal engine crane if you take care, as I managed to do this with my CSL.
I suggest:
1. Remove bonnet to give access and jack up front of car to give access - have some redundancy here as you don't want car to fall on you;
2. Drop drive shaft;
3. Drop gear box, either with or without the bell housing attached - remember to disconnect the clutch and the cylinder;
4. remove radiator, fan, along with all wiring etc - the aim here is to give you room to move and lift the motor out;
5. Undo engine mounts - these can be tricky so if they have a top and a bottom nut on the studs i'd take both as it can jam otherwise;
6. Attach a length of chain via the mounting points;
7. start lifting - my first lift was just to get it off the mounts - then I reset and lifted it from the car;
This will leave you with a complete roller, assuming the 730 has essentially the same setup as an E9.
