Check the archives. There's one forum member who bought a crate 603.97x and installed it himself or had an independent install it. He'd know what it came with. Everyone else I've read about had the dealer install the engine so they probably never saw it or what it came with until it was all in place.

Umm... can't you ask the dealer?
