[70custom20]

Great build, thanks for sharing. I’d love to do a diesel swap into my ‘70 K20 someday. A couple of questions if you don’t mind? 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.
