the 2.74 have a bigger sun gear

Most lock-up 904's would have the low gear set, depends on the year. Not sure how to ID, but this old forum thread could offer some clues to the years.

It can be swapped into a conventional case, but not sure what all has to be swapped over with it.

Copy and paste. Look at the sun gear all the way on the left. It has a indented boss or ring around the top of it. The non low gear doesn't have the ring. I think if you remove the valve body you can see this . Old 80s police cars 360-318 had them check the bone yard for it. Also old cop cars also turned into taxi cabs so check there too. Hope this helps.
