Other than hanging cranks from the flywheel flange like Jerry mentioned, vertically crated crankshafts would be unstable (more easily knocked over) versus a horizontal crate. NOBODY would store or transport them in a vertical crate. I doubt that even a 20 ft drop would do more than some cosmetic damage to a 235 crankshaft.
For my 292 I paid $8500 for a billet crank from Crower. It came in a very nice felt lined wooden box designed to be horizontal.
