If you're going to do one side at a time, you're only lifting 4-500 lbs. From previous experience doing it in chassis you'll have more room to work if you lift only the side you're working on. I use a bottle jack, and a block of wood resting on the oil pan rail to lift it.

I know you probably don't need to be told, but use some blocking before you stick your hands in where they could get pinched, if for some reason the bottle jack would fail.

I've tried lifting it in the center, but it works better to lift one side at a time because tilting the engine gives you a little bit more wiggle room to work.

That's how I do it, others can chime in on their techniques.
