    500+ rwhp out of a 5.3?

    As the title says, I’m trying to get over 500 to the wheels NA. Is it possible with a 5.3? Or should I just start looking for a 6.0? I’m at full bolt ons right now and I don’t want to do heads and cam if I’m not gonna reach my goal. If I can just get close to 500 I’d be happy with that. Mods so...
