400hp 9.2ISL Cummins or 400hp C9 Cat
Pros and Cons please and do realize that some of this stuff is like arguing Ford vs Chevy. Thing is, I'm not even in the ball park when it comes to Diesel power.

Since a Cummins or a Cat are the most prevalent engines for MH's it's not something to fret about. Both are great engines. Noise??, I'm not sure you can tell the difference while driving. I hear a lot of both and they all sound the same to me unless the muffler has been changed than either is load outside.
I have a friend with a Cat 350 that I have been traveling with for four years. We have a ISL400 Cummins. I'm sure you can't tell the difference driving down the road. But, when we pull into a rest stop and leave our engines running you certainly can tell the difference. His is much louder than mine. That being said. He gets nearly a mile per gallon better than I do. Not sure if there'd be that difference if he had a 400. My coach is much quicker when pulling out on to the super slab. Probably the difference in torque.
