i bought two "lifting straps" at nrthern tool. they are the yellow nylon type, i beleive 4 feet long ech. they have a loop at each end. "basket" style they hold 3200 pounds and choker style they hold 1650.
i put them under the block with the oil pan still on and hooked both ends in the hook on the chain fall. i just tried to space them evenly to where the motor was most balanced. it worked perfectly to suspend it to attach the engine stand to it.
