Computer programming is where the HP difference comes from.

Jlehman,

Here is a link to Cummins. At the bottom of the page, it talks about the differences between the SO and the HO.

Programming and gallery-cooled pistons. I've never taken either one of them apart so I'm not sure if there are any more substantial changes than that. Perhaps someone with more experience with both of them will chime in.

About the only substantial thing you are missing is the "J" jet to help cool the piston. All the other differences are software related.
