I'm not saying it can't be done, but unless your VIN shows your truck as a "glider", then it would be illegal. The problem is you are going from a full blow emission year truck to a pre-emission engine. While it is not as obvious and a DD15 that has been deleted, a good number of large shops won't work on it due to fear of heavy EPA fines.
