You'll need fuel rails/injectors and I'm pretty sure the injector plugs are different.
You'll also have to modify a few things on the truck accessory drive or the throttle body won't clear them. It's not a simple swap but not hard either.Or switch to the LS3 accessory drive. http://www.ebay.com/itm/LQ-Idler-Pulley-Relocation-Bracket-With-Belt-LS1-intake-Manifold-Swap-/170914739046?pt=Race_Car_Parts&hash=item27cb4ff366&vxp=mtr
