Building a 5.3 looking for horsepower

[todd7498]

I have already done a LS swap in my 72 last winter and love it, only issue I have is I want more power. I installed a 4.8 last winter because that is what I had with a 4L80E. I have purchased a 2007 5.3 now and want to build it for more power so I am looking for recommendations on building it to get as much power as I can for daily use. So if anyone has any recommendations on cam shaft, stall converter etc. please share what you think. Thanks
