    Any experience with this model of Cummins would be appreciated. Ive read that squeezing 574HP out of the original 8.3's risk a lower reliability than the other Cummins models?
    Thanks!

    Rock solid.

    Keep the coolers clean and carry a spare Sherwood saltwater pump. Other than that, you've got you're self a unit.

    Were managing QSC HO 600 and 500s. Of course you do not operate at WOT all the time but these are bomb proof 8.3s.
