LM7 swap to aluminum 6.2 questions
Working at a dealer sometimes we come across cheap cores. This is the case this week. I might be able to get my hands on a 6.2L out of an Escalade for $300 (dropped a valve)
My thought would be to fix the valvetrain & piston if needed. Drop in a performance (non VVT) cam, LS9 headgaskets & ARP hardware and get it ready for forced induction.
The added displacement & lighter weight would be great but i'm not sure if the GEN4 longblock will swap in to my 05 alright?

Yes it will!
You will need the conversion box from lingenfelter, this will make your PCM capable of reading the 58x reluctor wheel and crank signal vs the 24x that it reads now. This box will also extend the cam sensor to the front of the engine an make that signal readable as well.
You will need to get their knock extension harness as well. This will relocate your knock sensor connectors from the valley down to the skirt of the block. And to use your GEN III sensors you'll need to drill/tap the knock sensor holes to accept the thread-in sensor instead of the bolt-thru type.
You will also need to delete the VVT system (hardware wise) from the engine... Search my posts in the internal engine section to find all you need to know. It's a very simple swap and not too expensive.
I'm in the middle of doing a 4.3 V6 to GEN IV V8 swap on my 01 truck right now so I know what you're up against.... Other than the stuff I mentioned, you'll obviously need the matching intake of your choice, adapt the fuel system, and probably an x-link to run your new larger throttle body.
I think that pretty much covers it, everything else should swap over.
