Whether the Hummer H1 Duramax LLY engine is different than in Chevrolet Silverado/GMC Sierra? If so, what are the differences?

They only came wit 6.2L and 6.5L Detroits and still do for the military versions. Any with a Duramax were conversations.

I thought the overall dimensions were smaller. I understand that there is no difference whether to buy Duramax LLY from Chevrolet Silverado / GMC Sierra or Hummer (except for the engine mount)?
