You'll also have to swap out the PCM (Powertrain Control Module). While you have the 3800 motor out it would be a good idea to change the intake manifold gaskets and the valve cover gaskets. These motors are currently under recall for the front valve cover gasket leaking and possibly causing engine fires! It's GM recall number 15757 if you want to research it further. Leave the top "beauty cover" off the engine as well. That's also part of the recall. HTH. -Jim
