4.8 Swap/Arctic White C10

[TurboDemon]

finally doing a ls swap in my 81 c10 (87 front clip)! Been wanting to do this for a looooong time. I have a donor truck, it's a 2004 model with a 4.8 in it. it was my work truck and i will be swapping that motor in it. So far I almost have the motor out of it and i've already made my wiring harness stand alone and had my PCM flashed. The c10 currently has a 98 model vortec 350 in it, with carb/intake/headers and my rear main seal is leaking oil bad, and a TH400/stall/shift kit.

I have some other stock ls truck parts, and plans for the truck for now is to keep the TH400 but i'm leaving the transmission wires and plugs for a 4l80 hookup attached to the harness for future use if i decide to go 4l80 later.
It's going to have a returnless fuel rail out of my 04, and cable driven out of a earlier ls intake. Motor is going to be stock for now, but plans later will be to build a turbo kit for it.

I have some questions about the swap, maybe yall could help.

The truck has an electric inline fuel pump already, but im assuming its only at like 5-6psi sense it's carb equipped motor? I'm planing on running the bosch 044 inline pump, would I still need a sump out of an 87 truck or not since it already has an electric fuel pump on the truck.

Also do i need a different oil pan or not? I've heard different things and just not sure on this

I know i'll need to notch the frame for the A/C, but are there any part # for A/C hoses/PS hoses/Radiator hoses that i'll need to get?
