how do I search for a 7.3 Gas engine in a ford truck

7.3 gas Superduty trucks are still rather new and hard to find. I would try the Ford website and do a search in your area or stop by the local Ford dealership. The dealership can find what you want if it is out there,

Use the Ford website. When I did a search a while back I found a lot of them but things may have changed. I use the Build my Truck feature and at the end you use the search feature. Odds are you will find your truck if you do not mind traveling a few miles.
