Rent an engine hoist and pull the engine. Rent or borrow an engine
stand to mount the engine on when it comes out of the car (optional, but
recommended). It sounds like huge amounts of work, but in my experience
(having done 5.0 remove/installs countless number of times) it is the
most straightforward way to do it.

    Also, given the year of your car, your rear main crankshaft oil seal is
likely leaking like a sieve, and the only way to change that seal is to
pull the engine or transmission.
