I think the v10 used in the class c is the two valve. It looks like the numbers above are from the three valve available in the class a.
Having owned a ford f350 with a three valve v10 and a class c with a two valve v10, I would say the engine is fine and does what you ask of it.
I would go with the chevy because of the modern steering and more cab room.
