I have a 2003 rcsb with a standard and 4.3. I have a 5.3 I want to put in it. What all will I need and where will I find it? Will everything (clutch, wiring, cooling) bolt up and work? Can you guys help me make a list of all of the parts or special tools I will need to make this work?

The best advice I have ever heard:... Only take B( . Y . )ST advice from someone that is CURRENTLY running a turbo setup close to, or bigger than what you want......
If you are not happy with the cooling system, you can replace it with an NNBS radiator. Very little fabbing involved. The new radiator is 34" approx. There is a guy at another forum that did this and it looks nice.

I believe you have to get new radiator hoses.
