    08 ls2 into an 02 1500. What's involved?

    What all is involved to swap an 08 ls2 into an 02 4.8? Is it direct? Or what problems could I run into?

    the big one is going to be the reluctor. the ls2 is 58x, yours is 24x. this means you need to swap the entire computer, there may be an adapter or something on the market though...

    Well it's not going in mine. Someone I know is wanting to buy the ls2 tomorrow but I told him I didn't think it was a direct swap so I was wanting to double check

    I know about the fans and stuff that is simple stuff. And I know you can use the harness and PCM. I just didn't know if there were any major complications.
    Since this engine doesn't have an intake will the truck 02 4.8 intake work?

    sorry about the mixup... other than reluctor the intake should bolt right up although just tell him 2 go ahead and spend the lil bit more money and get the l76 intake...nothing really major tho.

    There are a few things....the reluctor wheel needs to be changed from 58x to 24x. Or buy the electronic box. The Cam position sensor is on the front of the block and the wires will need to be changed... just swap A and C. The knock sensors will have to be relocated to the sides of the block. If the motor has DOD or VVT that will have to be removed. Also a possible lifter and tray swap and valley cover....
