int or ext fuel pump
the engine is a 6.0, LS3 heads/intake, and a Procharger
using stock LS3 fuel rails, so i would run a return reg
prob ballpark 525 RWHP, not a max effort deal, but i would prob size the pump for 800 FW HP
The baffled/sumped caprice/impala tank with an upgraded intenral pump is worth considering.
I have one and it did come in handy once already.. had a loose ground inside the sender to the pump. was cutting out on me. was able to remove the access panel, fix the ground and be back on the road in 45 mins... you can see mine in my project page in my sig...
You can always go with twin internal pumps if you feel one is not enough.
