manholt Report post Posted January 17, 2020 Factor, DD60, 515 is a good engine. So is the Cummins 500 ISL. Don't worry or be impressed by HP & 100 Ft. Lbs, bigger the HP=$ at pump. Also, a 525 will get to max torque about 10 seconds before the 500. Share this post Link to post Share on other sites
wildebill308 Report post Posted January 17, 2020 The only problem with buying used is you may need to look a long time to find that optional configuration. I think I am going to see how a Cummins ISM 450 with 1500 lbs./ft of torque workes out just for the fun of it. Bill Share this post Link to post Share on other sites
manholt Report post Posted January 17, 2020 Bill, if you find that engine, let me know! The 425 gets 1,550 torque...the 450 is 1,450 and the 500 is 1,550! The M11 evolved into the ISM & it was built up to 2010. Mine is the 2009, 425 HP! Share this post Link to post Share on other sites

I will need the serial number to accurately verify what the Cummins website says. They show the 450 and 500 ISM at the same torque. Bill Share this post Link to post Share on other sites

kurtsimon Report post Posted January 9, 2022 (edited) I have a 2008 Monaco Executive with the 525HP ISX with 135K miles. What can I do to make sure I don't have a failure from the valves or fuel injector pump on the road? Can I replace the head/valves with a rebuilt? Can the injector pump ceramic problem be preemptively fixed? Kurt Edited January 9, 2022 by kurtsimon clarify fuel pump Share this post Link to post Share on other sites

If so they can recommend a place to have it swapped with the updated design Share this post Link to post Share on other sites

manholt Report post Posted February 23, 2022 The list is already long! I have the new and improved version of the 600, to my knowledge, Cummins don't make the 650 anymore! As RayIn said, but that's only one out off 100 or perhaps a thousand, that you never will hear about. 🤬 Share this post Link to post Share on other sites
