    That's what my thinking is, but that's why I thought I'd post it on here.

    Buying another engine is more expensive. I will do that if we must, but I'd rather not. If I do that, I'll put a Detroit in it.

    I have made 600hp to the ground with a n14 that started as 430 i beleave it was with no parts at all and yes his is 350 so 500 is not going to be possable without some kind of parts. But the best way is to rebuild it with the 500hp parts injectors cam pistons and all then reprogram the ecm. to make it a true 500hp to the wheels.

    If you do not have a "red head", you mechanically will be limited to 460. Mine was a 410/370, and I had it turned up to 460. It was a pulling beast, even at "only" 460.

    i think that would have been because of mechanical limitations rather than an ecm one. a red head in itself is just parts, so i can or should be able to put those same parts on this one. i'll find out more tomorrow.

    Just got off the phone with Cummins. I have a CPL 1807 and it needs to be changed to either a CPL 1944 or a 2003. Both are 500HP. Injectors and pistons is the only hard parts that change.

    i would say you are correct, but since i'm going to rebuild it i might as well go ahead and buy the higher hp parts anyways.

    If you are anywhere near SC I have some N-14 engines for sale. Have a red top sitting in the shop already out that a guy bought from us to have put in another truck but he never did it. I am ready to get it out of my side stall.
