I have done it before , i prefer to pull out as 1 unit engine + box , i find it easier .
I dont know if your engine crane will lift high enough for the 2 units tough , i lift with a chain block . you will need your hoist to be able to lift about 2.1 meters ( from the floor to the hook of your crane ) . Others undo the box and drop it under the car and like in Duncans case undo the box and leave it there .
whatever you do you will need to tilt engine box to get to the top box bolts and to make it easier to undo the top starter bolt . I leave everything on the engine , just undo the air comp and secure it on the rail do the same with the steer pump .
Just the normal stuff , undo everything , take radiator out drive shafts , undo all hoses take airbox out .
hook your chain on the front and rear hooks or use a strap around the engine .
One person you will need almost all day and then a helper when you lift it out .
