Officially Swapping in a 6.0/2wd 4L80e into my 99 OBS Escahoe - GET DA WATER

[foreverfalcon40]

Just got my oil cooler lines in.

Tonight going to order my Mag Hytec Deep Pan, Transgo HD2 Shift kit

I was originally going with Schoenfield Conversion Headers...but Since I am 2wd I have a few more options...like Actually NBS headers....

What you guys think? I WANT THE TRUEST FORM OF LONG TUBES

Amazin ATS LOL nice one.

I went to order my schoenfeld headers...I can only find for 2wd trucks.


What is out there for 4wd trucks. I am swapping in a 2wd 80e...but I am still retaining my torsion bars. I do not have a transfer case & front drive shaft.

Ended up ordering the Painted Headers off of Amazon like a $50 difference plus free shipping. Then they got me with sales tax which I never paid before. Still came out $15-20 cheaper then anyplace else via Ebay, Summit, & Jegs.

I got painted as I didn't trust the Armor Coat Ceramic Coating. I <3 Black!
I will start test fitting the motor and trans. Once that Is complete and header's have been massaged into place I will send them out to get Ceramic Coated in Black!

Thanks!

My build has come to a halt due to the fact of cold weather. There for I can't clean up, prep and paint the engine bay.

I think I have everything in order...for the swap ( think) EXCEPT FOR FUEL

I want to tackle the wiring harness b/c IMO this will take me longest.

Where is the best HOW-TO-Step by step process. I am an amateur when it comes to wiring and reading diagrams. (Running lights and gauges is my specialty...anything after that I am a fish out of water).

There is a sticky on the forums for wiring, is that what you guys have used?

Little bit confused your using factory 411 computer and harness, but buying all these LS2 sensors I'm assuming all these sensors plug up?

I am sorry for the confusion.

I have a 99 OBS Chevy OBS 4x4
I also have a 411 PCM that needs to be installed. Install is easy (just time consuming) need to take each wire and just re-pin it.

What is going in...
6.0, 2wd 4L80e, E-Fans from 06 Sierra
I have the Harness and PCM out of the 00 Chevy HD in which the motor and trans came out of
