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.

It's hard to quantify, but I agree with "sprintmod1" on the two engines. My sister had a 34' DP with the 350 Cat. I had a 36' DP with the 400 ISL. Their coach was quicker, but I soon pulled away from them. When we would fuel up, I always look a less, (about 1/2+ mpg better) even though I had a larger coach and engine.
I know many of the older 525HP Cats, drank a lot of fuel. I don't think you can go wrong with either engine, but my vote would lean toward the Cummins.
