HeyYou is right on point, except for one thing. The 96-97 diesel PCM will run your 97 gas dash perfectly fine. We swap gas dashes into 12 valve trucks all the time because the diesel dash only reads to 4,000 rpm and more and more trucks are running 5,000+ rpm governor spring kits.

Trans is diesel/V10 specific bolt pattern. If you're piecing a truck together you can get a V10 trans, just make sure you buy a new diesel torque converter (which would be a good idea to grab at least a billet single disc anyways). Your transfer case would work, the output shafts are the same 23 spline on the 47RE vs the 46RE. Only the manuals and newer 6 speed autos run the bigger 29 spline output shaft. However, I would highly recommend confirming that your truck has the NP241DLD. If it has the NP231 I would look for the 241DLD for simplicity in swapping since your current shafts and yokes will fit. Though if it has the 231 I would also suspect that it has the lighter axles, if that's the case I wouldn't get very carried away with adding much power to your Cummins or you'll find your weak points in a hurry.

Think there will be any benefit to such a system?

The 60 out back will take a pretty decent beating, would hold anything a fairly stock 47RE will. Billet single disc and a decent VB or shift kit will hold 300-350rwhp relatively reliably and that happens to be about the max you can squeeze out of the stock turbo and injectors.

You might have to enlighten me on this s chip you speak of. Up until recently I would have immediately said there's no such thing as a chip for the 12 valve. But recent advents have produced a couple gadgets for them that kind of acts like a chip. What I have seen of them good tuning and a little ingenuity can accomplish the same thing for $30.

You can set it to manipulate the engine so to speak. Say you need more power for hauling you set it for that ornif you are casually driving on a trip or through town you set it for fuel milage.

I just recently found out a 12 valve cummins is not set up for a chip so i cannot use one, or at least as far as i am aware of. The only way to tune a 12 valve cummins is manually is to do it through the AFC springs, fuel plates etc so my idea for a chip has been thrown out the window sadly.

Good deal on the Dana 60 front, you're golden drivetrain wise then, that's pretty much a guarantee that you'll have an NP241DLD transfer case too. If you do decide to replace the rear axle later on, don't waste your time with the Dana 70, look for an 80.
