Swap:just got an L96 LY6 2014
I need to swap my 2003 5.3 it's spitting oil out the dip stick. So I got the 50k motor out a 2014 GMC Sierra 2500. Harness, Computer, Starter, Alternator, A/C Compressor, and Power Steering Pump. I do have a Procharger on it as well. Also a 4l80e trans. This is the flexfuel one. So what would be the best way to get about 700hp at the wheels ? I know I need a cam and springs. I am running about 10 to 11lbs of boost. Any help from you all is needed input wise. Also can I make the 4l80e work with this motor? Thanks for any help! Rick.

Well you just created a giant headache for yourself depending on what route you wish to take.
The 2014 engine/harness and computer will not function in a 2003 body nor can make that E78 controller work with a 4L80e. That computer talks on a can-bus data system with the PCM/TCM/BCM and whatever else to function properly. Also that controller is very unique and must not be taken lightly with the airflow and torque model that requires very precise tuning.
So back to what you have and what you can use. Take that engine and swap reluctor wheels on the crank. Remove the oil pressure relief valve in the pan. Remove the VVT cam and install a regular cam because your computer can not use a VVT cam. Swap front covers. Drill and tap the block for new knock sensor placement. And I'm sure a bunch of other random things too.
Or just rebuild your engine and sell what you just bought.

Swaps can always be done but everything has to work together.
The main problems is that you have a much older truck that you want to swap a much newer drivetrain and controller into while not using the original transmission or cab-bus features.
Honestly you are better off finding a LQ4 or LQ9 engine that would be a direct bolt in swap.

2012-2017 Silverado 2500/3500's and Sierra 2500/3500's that run the 6.0 all use E78 controllers, posted that in my first post.
They stopped using the E38 computer in 2011 in the heavy duty line up. Only half tons, SUV's and the GM cars used the E38 up to like 2014/2015 depending on vehicle.

You could easily swap to an E38... but then it still doesn't work with your truck. If you want to drop that L96 into something earlier fine but for all intents it' just not what you need for your 03.

I'm not the smartest when it come to this, but I get a little perplexed that they are making it work in earlier years.. Can it be used as a stand alone?

You can do that if you are really bent on making all this work. Cruise control I am not sure what they did there.. probably deleted it.
Early stuff has no Bcm in it... no data communications for HVAC systems..... nothing. So swapping even a GMT400 is pretty straightforward.... older than that is a cake walk. But these..... well have fun!
