either shrink rap or band to a pallet deliver to truck depot they will unload with forklift weigh and charge accordingly the ones i shipped range from 60.00 up to 125.00 depending on where it ship to and if its a business or residential address cheaper to pick up and deliver at the truck depot
I built a wooden crate out of two pieces of ply and 4 2x4's. Drilled two holes in one plate for the timing cover dowels. The other had holes for the bellhousing dowels. Slid that into a cardboard box and mailed it through the post office as a 125# box. It was just light enough to not be considered 'freight' and stuck with the higher prices that commands.
I found a small square pallet and drilled holes in it and bolted it to the bellhousing bolts. Stood that up on end and wrapped the rest in cardboard. Ups will ship a bare block as regular shipping. Its a weight surcharge but its better and easier than truck freight. Mine had a timing cover and oil pan bolted to it.
