    At what point in 2004 did Cummins change the engine rating to 600 lb./ft of torque, and looking at the engine data plate, how can you tell? My engine says ISB 325 but mentions nothing about a torque rating. The truck was manuf. in 8/04 and the engine 7/04. Sorry for the dumb question. Thanks again for the help!

    If your motor is rated at 325HP than it's got 600ft lbs.

    I bought mine in feb of 04 and it was a 600. Kinda dissapointed that my 06 is only 610 when the mighty dmax is 650. I hope I don't get burned with a half year.
