So I am starting a thread to detail the upgrade of my truck from its 280k mile 5.3 with recently replaced castec heads on it to a bigger more powerful engine.
I will be picking up an engine (Probably before I repair the rear end in my truck).
I have a couple engines I will be looking at this next week. They both are out of silverado 2500's so I expect them to be LQ4's.
I WELCOME any suggestions and corrections to what I am looking at. Other than the machining I will be doing this build myself. I am still researching parts to do this. Yes I could buy one already prefabbed but I expect I will be breaking parts down the road so I want to know how to fix stuff myself.
Plus with what I do at work currently my skillset has improved to the point that rebuilding a motor or transmission doesn't scare me anymore.
So I expect to do this engine in three stages...
1. Disassemble, machine as necessary and assemble the bottom end for this new engine. Will use forged bottom end and looking at going with a stroker kit. Not sure if I should go with a 408 kit or smaller. Will be looking for one that doesn't need any machining of the block for clearance. Will assemble and install into truck.
2. Top end work... Will look at better heads and cam for my truck knowing that I will be adding a Magnuson SC in the near future and building with a mind to using E85. I understand E85 just requires an injector upgrade.
3. Getting a Magnuson blower kit for this truck.
I will be using HP Tuners to tune this truck and I will upgrade the fuel pump and injectors as soon as the truck makes it known I need them. When I swap them out I will be swapping for the size I expect with the blower on it. Hopefully it will support such a feat so I don't need to change them out twice.
Edit: Note, The link to the H2 Rear end is here:

Thanks to the member who pointed this out to me! Now to look for a SAS that will work with this truck and use coil over shocks...
