I installed my engine together with a three-speed plus overdrive. It's not hard, especially if you have one of those "adjustable hoist" deals that lets you change the angle of the engine/trans as you need to. Dropping in both at once sure saved a lot of time and knuckle skin later on.i dont think you have room to do that, engine and trans together are pretty long and have to go in the engine compartment at a step angle
