Just something to think about. If you're going for more of a factory setup, GM route is fine.

Thanks again for the info, I do appreciate it.
I will definitely take a look at the Holley system. One thing I will also need to consider/research is that at some point I would like to upgrade the stock truck intake and injectors. If I buy the harness now, will the connectors for the fuel injectors need to be swapped or changed for different injectors?
