I have a 2001 Ram 1500 and was looking to buy a new or remanufactured motor for it. I bought it new with a 3.2L V6, but all the websights I visited only listed a 3.9L V6. I am really looking to upgrade to the 5.2L V8, but found this very curious. After decoding the VIN, it has the code for the 3.9L but it's a 3.2L under the hood. Can someone shed any light on this for me?
