I think there is a little more to it but even so just a main shaft swap with rebuild costs more than just buying the Dodge trans I'm finding.

I appreciate the insight DieselSJ. I am definitely sticking with the diesel build plan but I may have to scrap the use of my NV/205 combo. The Allison will be great, I was just hoping to save a few bucks by running my existing drive train especially since I like to row the gears myself.

If it is a post '94 GM NV4500, all you need to do is swap to a Cummins input shaft - the main shafts will work with either input. To do this you're looking at about $150.

If it is a pre '94 GM NV4500 with the wider ratio spacing, it would be more involved to make it bolt to a Cummins.

I was wondering if you contacted Banks on their crate engines? I called today about them and they said that they didnt really have the program going yet like the 2012 article I read. They were coming up with this idea since they were getting the contract to put Duramax engines in the new military vehicles taking the place of the hummers. He said that they were focusing on the new 2017 model engine. He projected engines starting around $19,000.00. Was still working on accessories brackets and stuff. Let me know if you know of anything different.

You could buy a complete high-mileage truck and do a wicked build on a Dmax for less money.
