Remove the bonnet, radiator, carbs, remove battery, disconnect any wiring (starter, coil etc) undo the exhaust manifold from the head and if you can undo the manifold from the front pipe, tie up the exhaust.
Start to unbolt the engine mounts. Lift the car and remove the dust shield at the bottom of the gearbox. Remove gearbox to engine bolts accessible under the car. Lower the car.
Attach your engine sling/chain hoist/crane, support gearbox, remove remaining bellhousing bolts.
Now the fun starts!! Begin to lift the engine whilst pulling it forward, you may need to use a prybar to separate the engine from the gearbox, lift engine being careful of the paintwork (on the car, not the engine)
See, that was easy!
You may find it easier to remove as many ancillaries as you can to aid access and just make the lift easier, I'm talking about things like the alternator etc, just look and see what can be taken off.
