In your opinion, what are the pros and cons of using the Duramax engine vs. the Cummins engine? Is there a transfer case adapter for a new process 205 that will bolt onto the Allison transmission? Or is there a bellhousing that will bolt to the back of the Duramax to allow the use of an NV4500 transmission? I’d like to try to plan out my build as much as possible, like you said, if you plan ahead, you can save money.

I have been researching the NV4500/Dmax combination for a while now. Seems that it can be done, though details are sketchy. Someone had to grind a bunch out of their bellhousing and weld reinforcements on the outside, and someone else did it with no bellhousing modifications. Still trying to track down the people that did it to get more details.
