Mandate 2000 Cummins isx 600hp

[mkj5252]

Was trying to get some info about a 2000 Cummins isx 600hp motor and I live in Atlanta Ga. was wondering anyone know any good mechanics that service on these particular motors and also a good inframe mechanic just in case I need one in the near future. I was told by a mechanic over the phone they were not good motors and if I ever needed a inframe switch to a different isx motor instead of the one I have in the truck now. I’m use to driving with a dd15 and this is my first truck as an owner operator not a lease operator thanks.
