Building the truck GM never did..
I never suggest going over 100 shot on stock motors. It's a good starting point. But turbo is much better. Tell ur dad to go boost. Even sts is better than the bottle. have fun

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......

Limits of the 4.8 are dependant on multiple factors. With twins you could get 1200 HP as proven by a magazine (name escapes me). As for N20, I would feel safe on a 100 shot nozzle, 150 with a spot on tune, and maybe 200-250 on a direct port setup with its own fuel supply and a good tune. All that said, I'm not spraying but I intend to in the near future while I'm building another engine for forced induction. Do some research and plan what you want to do. Just remember, you can only have two of the following: fast, cheap, and reliable.
