    There's a 6nz can't remember which way it goes...500 and above or 500 and below on the last digits on the serial have bigger injectors, heavier duty pistons, bigger turbo etc. That can be turned up to around 750 on the computer with no parts change... that was coming from a Caterpillar tech...i figured like 715hp going off of the 535kw max on the data plate

    Also a 2ws with a marine cam, 58s, high output cat turbo, and a 7cz file on the ecm is pretty strong too
