4.8 Swap/Arctic White C10
 

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?

Your on your way! Start a formal build in the builds section if you haven't yet. It'll be one simple place to post all your progress, and a reference point anytime questions come up (for you, or for us).

Nice start to your build. In regards to your fuel tank/pump question, I bought a new '87 tank and sender and installed a high pressure pump so I could have a sump in tank pump set up. I was concerned about starvation at lower fuel levels, that was my reasoning for the sump. Pic in my swap thread.

ok thanks man, where did you get your new tank and sump from?

My PCM came in yesterday, and I got the motor out tonight. I still need to get my oil pan, adapter plates, fuel pump and other stuff. Haven't ordered any of that yet

any updates? I used dirty dingo slider mounts in mine. I would also replace the factory motor mounts while you are there.

Yeah I'll probably do that, still waiting on a few small items to come in, but I'll try to get some pics tonight of what I have so far. Got the wiring harness off the 4.8 and tranny detached, but I need to clean up the motor. Been real busy, I'm building a new house and have 6 month twin boys at home also, lol.
