Diesel Bombers - I want to build a Chevy Cummins!!!

I have lurking here for a while now. But, I'm am ready to become fully committed, lol. I'm Rey, from Orlando, FL, but currently stationed at Holloman Afb in Alamogordo, NM and I have a problem. I currently own a lifted 85 Crew Crew Chevy k30 SBC/th400/np205/4.56s/D60/govlocked14bolt that I would love to drop a 94-98 12 valve w/ nv4500 w/ my np205. I don't plan on towing with it or anything it will be a dd/weekend toy. I have little to no experience with diesel I just drove one and instantly fell in love. After doing some research I have a pretty good idea on what I want to accomplish. With build and just to have a fuel efficient on and offload beast.
