I have seen plates that mount to the carb location on some intake manifolds that are made for lifting an engine...not sure if they would lift an engine/trans combo, but have seen them used on American V-8 engines.
...not that I would not have reservations about them...no idea how much bolt engagement was available, but if they would be used on an aluminum intake (and I can't imagine them not being), I'd worry about stripping the mount bolts.
Ford's 351 Cleveland came with lifting rings attached at the factory on the front right and left rear exhaust port locations, have you thought about using those holes?
Cheers!
