I would think LT4 injectors would work. They make 650hp on a 6.2 from the factory, so a smaller displacement 5.3 should have more headroom. I think you could use the LT4 HPFP too. But I don't know what guys replace the low side pump with.

I'm currently making 650 to the wheels running the LT4 injectors, LT4 high pressure pump. and a Walbro 450 "Hellcat Pump" in the tank. I'm looking push a little more boost and hit 700whp with this set up... if not maybe voltage booster for the pump, inline pump, or some other dual pump set up... well see...
6.2 texas-speed stage 2 cam and LT4 supercharger with all the other bolt on bullshit running e85. I think this is the most reasonable and reliable set up.
