There are quite a few differences. The fan shroud housing, the PCM has different programming (3 different shot of fuel per combustion evolution)and controls the turbo's wastegate. 4" exhaust, different air filter routing supposedly to keep the air cooler in the air box, meets California emissions. I'm sure there is more that I am missing.

Here is the link to the CUMMINS site that talks about the 600.

Also, I think the 600 is drive by wire, No more throttle cable.

All 24 valves are drive by wire. I know that for sure because when I installed my Big Hoss I forgot to plug the TPS sensor back in! As soon as I hit the go pedal, the engine light came on and of corse it did not go. After plugging it back in and resetting the code, everything is fine.
