Ly2 swap starter questions Ok guys so i have a 2007 silverado z71 extended cab with the ly2. I picked up an 2009 ly6 for a pretty good price, complete pull oit beside the harness and ecu. I have a couple questions.
1. Since my engines are same gen, will my ecu and harness swap over?
2.I know the vvt plug isnt there on my harness, but as my daily driver i would really like to have it. What do i need to do to get it if my ecu or jarmess do swap over or do i just say damn it all and get a harness an ecu?
3. What is a really good header company?
4. I know the engine is good, but its used. What should i do to this engine to make it last the longest i can. (Not really a professional) but would i beable to pull the whole thing apart and clean it? Is that necessary? What should i replace if anything?
Any info or direction would be great thanks

1. Yes, they'll swap over. You'll need to delete the VVT on the LY6 and retune your ECU to run it. Everything else should swap over fairly straight forward.
2. See #1.
3. As long as its a stainless header made for your truck, I wouldn't be too picky. No reason to buy an $800 set of headers unless you plan on big power.
4. I always just seafoam my gas tank and maybe suck some windshield washer fluid into the intake to help clean up the valve/rings. If you feel like replacing anything, swap the lifters. Its always a lot harder to do it with the engine in the vehicle.
5. Where are you located? I've been looking for an LY2. I might take it off your hands if the price is right.
