Check to see if you have the 'bolted in' removable upper engine bay diagonals. If you have, note their position and take them out.
When I fitted my engine it went in with all the ancilliaries attached, including the Rover throttle bodies.
It is a tight fit at the front but it just comes out if the angle of your dangle is correct.
I have a 'load leveler' if you need it plus some attaching brackets and bolts for the chains.
Do not forget the speedo drive, it is delicate. If you can not undo it in situe remember to do it when the engine and gearbox are half way out. (Same when you refit it)
Also take the reverse gear light switch out. It is easy to snap it off when jiggling.
Yes you need the gear lever out so the tunel top has to come off. As said above it is usually just a push fit with two self tappers at the rear.
Good luck, have fun.
