I've done it in a garage by myself like this. Rope hood to rafters. move truck back. Lower hood onto cart and move out of the way. Move truck back to work area. Drop in engine, lower tweak use wood block straps and any means to keep the thing on trajectory as you keep adjusting and lowering. I've dropped in a few engines on my own, it's really fun ha ha. After engine is in, set the tranny on your roll away jack. If you have 4x4 you can get under there easy, else jack stands. Now jack up the tranny, you have to move it around get it balanced just right and then rassle and fight with it. It will get tired and you will eventually win. Do the same with the transfer. If you are clever, angry and don't give up you can do it all yourself with just a cherry picker and one jack.
I once got mad and put a piece of plywood on my chest and while on my back let a 465 rest on my chest then shoved it up in there. Used my knees to knee press and everything.
When I was younger and my trucks were down, I didn't work; that's motivating.
