One option is to get one of those cheap engine stands and bolt it to a sturdy pallet. I had a boat engine rebuilt and the builder shipped it across the country like that. All worked fine.
Alternatively look around at the large plastic totes you can get at hardware stores or Walmart. I shipped the block out to the builder in one, it was cheaper than crating and a lot less time/hassle. Not sure if you'll find one to take a fully built engine, but worth a shot.
