Any issues with swapping a 2000 Dakota 4.7 litre with California emissions with a 2002 dakota 4.7 litre without California emissions? I know the 2000 had 3 converters and 4 O2 sensors and the 2002 had one converter and 2 O2 sensors.

 

You're going to run into electrical issues as the tone rings inside the block changed. You'll need to verify that both engines are 16 tooth before swapping.
