I'm definitely interested to see how it turns out and how much work it takes along the way.
I thought about putting a 6.5TD in my truck because they have great fuel economy and ok power. I didn't put much consideration into a Duramax because I didn't think it would fit without a really big hammer so I'm very interested to see what you have to do on yours.

I already have the 6.2 and transmission from a previous project (2000 Silverado RCSB). Wiring that was a pain because of the two different protocols. It it was a beast when it was done. Putting it in my 72 should be a breeze compared to that.
