Hi, first post here. I have a bone stock 2003 lb7 and the engine over heated and pretty sure my head gaskets are gone. Also have a couple transmission codes. So my question is, theres this guy who's selling the whole 2004 LLY engine with the transmission and transfer case. With all the electronics. Can I put the whole drivetrain in my truck? Anything special in would need done? Or could I just swap everything out? Itd be about the same price to fix my truck as it would just to do the swap. So my big question is, can it be done?
