    Just wondering if this is even realistic at all. I have an International single axle that im going to be into deep after doing the motor rebuild and to top that off I don't really like the truck, I should have bought a tandem for my area. It actually has the heavier 12,000 front axle. The frame would have to be lengthened about 4 feet!

    Dont bother considering it further.
    Its not practical nor cost effective.

    If your concerned about the motor buy a comparable tandem and swap it.

    Sunk costs :) They suck but they make logical sense

    would adding a drop axel help? its a good strong motor and should put you close to carrying capacity of tandem but less headaches.

    Don't do it, think of the phrase - 'throwing good money after bad'. You will never get the money out of it. You don't have a heavy enough front, should have more like an 16-20,000 front. A DT engine should be cheap compared to other engines, I've heard $3,000-$5,000 for an inframe.

    That is a lot of $$$ sounds like either the liners have pitted out or your o-rings have failed on liners.I have built many DT 466 engines something usually causes this like overheating,injector on that cyl, A complete re-man kit should be around 2 grand that is a lot of labor. The injectors are in the neighbor hood of $650-700 ea plus core.These are not included in a kit just new inj. o- rings .Good luck with it.

    You'd have to extend the frame.

    Beef up the current frame.

    Add an axle.

    Did you want it to be a drive axle? Add a bunch more cash.

    Plus, the registered GVW in the door frame would not change.
