Re: fuel upgrades for cam swap?
Depends on the engine choice and cam choice. The 381 pump is usually fine for most basic setups. Stock injectors are a bit limited, but a 5.3 with a medium cam will survive alright with them. A 6.0 with a huge bumpstick will usually want a bit more fuel than the stocks want to supply, or you'll end up with a large enough duty cycle % that the injectors will not like long-term.
