2014 ISX15 600 QuickServe question

[Flatbed]

I am in the process of swapping a 2012 ISX15 485 (2250) over to a recently overhauled 2014 ISX15 600 (2350). Rawze hooked me up with the file for the conversion. The 600 came out of a wrecker and the plate on the engine says ISX15 600, however QuickServe dataplate shows the model as a ISX15 550. Not that it really matters, but I am curious if there is a difference between the two? Were there certain configurations, such as wreckers, that were turned up?

That vin# comes back to that engine ser#. They look one in the same to me.

And no, there is no difference simply because the sticker itself says 600 instead of 550. The engine ser# and CPL# are what counts towards what mechanical hard parts are actually in it.
