my prefered lifting weapons are old seatbelts, ratchet straps and chain.
what you really need is a meter or so of really good chain with links big enough to get a bolt and or D shackel through then youo can ether put d hook through the chain and engine lifting eye or put a bolt through the chain and into the engine, or wrap the chain around things and lift if needs must.
i lift a lot of engines out on the head bolts after pulling the head to find out what went wrong you realise the lifting eye was bolted to the head,
i allways find the small ratchet strap is usefull to adjust the tilt of the engine if working on your own on a tricky one wee the engine needs to be tilted and rotated to perswade it to fit in the hole.
seatblets mainly the middel lap belt just make good quick relese slings mainly for picking and moveing stuff about with
