If its a 2006 Cat its likely a C7 engine, which can be set for 300, 330 or 350 HP, just by changing the ECU options.
Which engine is better is a question with no answer, just personal opinions. What's more important is which previous owner was more faithful in assuring each fluid & filter change was performed as recommended. I would buy whichever one came with the best maintenance records from the previous owner (assuming there were no other deciding factors in the rest of the rig). An owner that keeps detailed records of all maint performed, is usually an owner that makes sure maint is done on schedule.
What does that entail? I have the Cat C7 that is set at 330 hp. If I wanted the 350 HP is that just a software change or does it require hardware too? How much should it cost?
Best advice is to call the Caterpillar RV Hotline with your engine serial number: 877 777-3126.
You could have a C7, or one of the last 3126's. Remember it depends on engine production date, not chassis or coach production date.
And, I would not get too excited about 20 more HP. I believe that torque remains exactly the same. Remember, the time you want more power is on those long climbs-- exactly the time that you are already stressing your cooling system. Adding more heat (which you WILL if you want more power) only adds to the cooling load.
