Geez I like Dennis's solution, I wish I'd thought of that! I sent a CB750K2 engine to Ace in Queensland last week, I was working at an Air Force base and scored a crate 32 inches x 24 inches x 24 inches, which already had a couple of 2 x 4's nailed to the underside to allow for fork lift access.
I also scored a nice light pine pallet, which I cut up and screwed on the inside of the crate (only had plywood sides) to strengthen it. I screwed another couple of 2 x 4's about 14 inches apart to the floor of the crate to rest the engine on so it wouldn't "rock", and cut the front out of the crate so I could slide the engine into it.
Once I'd used all the pallet material to strengthen it, I packed in a spare head, cylinder block, cam, cam towers etc, all individually wrapped in bubble wrap. (the cam was wrapped into an oiled cloth to stop it from rusting in transit) There had been some special stiff paper packing material in the crate when I got it, so I jammed that in every orifice, then screwed the lid and the front panel back on the crate, which I'd pre-positioned on my hydraulic "scissor lift" trolley.
I had no problem jacking the trolley up to the height of my pick-up trucks bed and sliding it on, and I forked it off at the warehouse at work. It only cost $126.00 AUD (about $80.00 US) to send thru a company here called "Smart Send", which wasn't bad for an 1100+ mile trip. I haven't heard back from Ace yet, but it should have arrived by now, they're normally very fast. Cheers, Terry.
