07 Newbie Q's...
 

Ok, where to begin...

My 01 p-pumped 24v has a blown ring (I'm assuming) and I stumbled across an 07 3500 drw qc 4x4 with a 6spd for $27k-ish that has around 29k on the odometer. It has a flatbed (which I need/want) and I'm assuming thats a good deal. I havn't driven or seen the truck yet, but will soon, and if all seems right, I think I'm gonna buy it.

I dont know crap about the 6.7s. I don't know if it has the nv5600 or the g56. How can I tell the difference? I've done some reading on all the deletes, but not sure if I'm willing to risk the warrenty issuses. I haven't talked to my local dealer yet to see how picky they are about that stuff, I will though if I buy the truck. I haven't had warrenty on a truck in close to 7 years, so thats why I'm hesitant to do anything to void it.

If my dealer is "cool" then obviously I'm going to do the deletes, but not sure what else I should do for what I need/want.

I pull 7-15k weekly and would like to optimize my milage loaded/unloaded. I know how to on the 5.9's, but not a clue on the 6.7's. From what I have read, a smarty jr (or reg smarty) sounds like my best bet. Any other ideas or tips? (I don't plan on ever going over 500hp on this truck)

It will be the G56. They swapped over from the NV5600 in 05(?) Im pretty sure. Assuming it hasn't been replaced that is. Check the shift pattern. If reverse is left and down its a G56.

For what you want to do with it a Smarty, a good set of gauges, and a good clutch will take you a long way.

Full deletes vs minimal deletes is a question of do you have to deal with emmisions testing, possible warranty issues etc.....
