Nick you are correct about the hood being shorter and sloped. The 357 is the same as a 379 short hood except for the 357 is fiberglass instead of aluminum as found on both 379's reg, and ex hood models. My truck had the Donaldson breathers instead of the Vortox ones. The Vortox units are alot bigger but sit lower on the cowl for some reason. The Vortox AC's also go down to the bottom edge of the cab an most of the trucks I have seen.
