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

[gagliano7]

The truck oil pan sits about 2 inches lower than the front crossmember on a 1992 2wd pickup.I bought my truck already lowered so i am not sure how much it is lowered but i have no problems.The truck is c notched in the back if that helps.

Thanks for the response. My truck is 4wd but going 2wd witht he 80e. I am running 22's with staggered tire size. But my rear is 305/40/22. Just have shackles in the rear. Once I get this thing running I have Hangers, C-Notch and Firestone Air Bags waiting to be installed. I can not go any lower in the front or else I risk bottoming out unless I do some trimming which I refuse to do. I do not want any debris getting in my engine bay.

It is getting warmer out...start the final stages of prepping before the actual swap.

For those who have swapped...Did you guys run the wires to the 411 or hacked up LS Harness? Keep in mind I am looking to retain All the goodies...A/C, Cruise Control and ABS

Thats where I am at right now. Cant decide on which way to go. I have all the info to go either way but cant make up my mind.

I used the original harness supplied with the 6.0. Modified it for my truck. I retained the A/C and cruise control. I'm sure your vehicle will be different with all it's accessories and difference in year from mine. It took some work but I felt it was worth it. It gave me a better understanding of the entire electrical system.

Ok, So finally after almost a year Lextech is finally sending me a pre-programmed 411 as well as A/C Bracket kit. Here is a link to all the info on it (http://www.ls1truck.com/forums/lsx-t...acket-kit.html) I wish Lextech was closer so he can do a live tune, but his pre-tuned 411 will help get the truck started and hopefully run smooth enough for me to take it to ForceFedEngineering (http://www.fferacing.com) to get it Dyno Tuned.

I needed my gear ratio and I was not sure so I finally looked up my RPO code and this website was the besthttp://<a href="http://LonestarThund...hunder.com</a>

So I have 3.42's from the factory. Also needed to know exactly what injectors I am using for the tables and 8.1 Marine Injectors by Delphi Model#17113739.

I picked up the injector's used also the seller got me (I think) in a vulnerable spot) Said he had modified fuel rails (welded AN fitting) help with the swap so for few extra bucks I got them as well. Figure just put less stress on my buddy who is helping me with the swap. I am stuck in a rut with the swap as it comes to getting the Fuel System squared away. Not sure if my Tahoe is return or returnless and same is for my 6.0.

What do I need to order or fabricate to help get fuel to the motor?

Here are the links to the fuel rail

I am personally leaning towards using the 411 with the additional wires for simplicity. If I can't get the wires to look nice and neat then I will go the other route. For now my heart is in re-using the stock harness and making it nice and neat!
