You might want to edit your title to reflect your actual question, it looks like you need help with a spun bearing, not engine replacement choices.

Easiest would be a 7A obviously.
Anything but an A series engine will require you to replace the trans and a whole bunch of other things.
Doable, but a lot of work.

A 4AGE version should fit in fine, though wiring would have to be done.
I don't know the specifics of what else would have to be replaced, but I can't imagine it being more than for an S series engine.
