No offense, but you are wwwaaaayyyy over thinking this..........it's a bare block......you want it in the back of your truck.......you appear to have a cherry picker(you got the engine out of the car).........the pick point is not that critical so long as it's stable........rope, nylon straps, chain, chain covered up with rubber hose....... bolted, wrapped around the block so you can get into the truck
I get that, apparently, you are doing this alone.
Your 4 inch ratchet strap would do the job, wrap it around the block, cinch it up tight, hook it on the picker, pick it up. If you can, just pick it straight up, back your truck in under the block, set it down, that way you don't have to worry about the load swinging.
