I think you should talk to Hammerhead on the forum here. He's one of our heaviest haulers. 9 axles may be some of his smaller stuff. He may be able to shed some light on what's a good setup and how long you can really expect to get out of the engine with that setup. Hopefully he'll be along and chime in. If not PM him and I'm sure he'll get to helping out.

There definitely are things that can be done during rebuild that will lengthen lifespan and make for a more reliable engine. Cutting counterbores and setting liner height to 14 thousandths, also torquing head down properly and Shimming the oil pump are a the big ones. Also you absolutely do not want to use any aftermarket engine components, OEM only.
