Actually, Navistar was thinking about buying the 8.1L back in 2006 when they were thinking about buying the Topkick and Kodiak from GM, but they pulled out of the deal at the last minute. The 8.1 design when to Powertrain Solutions:

They enlarged the 8.1 to an 8.8, and they sell that engine to Navistar for school bus use. They should offer that engine in the DuraStar truck, but for some reason they won't.

The new 4500 and 5500 will only offer the Duramax diesel at first, but word is they will eventually get a gas engine option. No idea what gas engine at this time.
