Fun fact: If you had a pet Chimpanzee he might only be 3 1/2 ft tall but he could pick up your motor and hold it for you while you change the oil. Max lifting power: 1200 lbs!
I just got the Harbor Freight 2 ton lift for mine. I'll store in on a pallet until I need to put it back in. Most engine stands are ok for a short time, but with our motors being so heavy (and long lasting) the stands tend to start collapsing after a few months. I wouldn't trust a 1000 lb version for long.
