+1 to the rubber mallet.

Also recheck twice that you have all the bolts removed from the case.  It's easy to miss one, especially the one in the front of the oil pan area.  Once you've got the oil pump out, and all the bolts removed from the case, I:

1. Flip the engine over (top case towards floor) & put it on something soft (like a junk blanket)
2. Put one of the long frame mounting bolts through the bottom case half with a heavy duty wire loop in the middle.
3. Put a 2x4 across two saw horses and hang a ratchet strap off it connected to the wire loop.
4. Raise the back of the case a little off the floor (blanket bunched up to provide a soft surface)
5. Grab a small section of 2x4 and hit that with a BFH around the case (don't hit the case directly with the BFH).

The weight of the crank & transmission will pull down on the top case, and the smacks transmitted through the board will loosen the case sealer.
