thanks, but its a late 2004 3.9, manufacture date 03/04. is everything same as a 3.8? I don't know but NO ONE has specs for the 3.9. can't get local ford to even check for me. most people don't even know this motor exist. must be like the chevy 396 that they over bored to 402 to close out bad blocks?
