Just don't expect Ford to pull such a trick on the Mustang out of the factory, because the 7.3-liter's iron block doesn't pair well with sports-coupe performance. Levine did say he expected to see the conversion at SEMA at some point.
The Raptor is another story. It's certain that someone will put the 7.3-liter in a Raptor, the question is whether Ford will be part of that gang. Ever since Ford dropped the 6.2-liter V8 from the Raptor lineup for 2017, Raptor lovers have pined for the V8. And that's even though the 3.5-liter EcoBoost V6 — shared with the Ford GT — outdoes the old 6.2L by 39 horsepower and 76 pound-feet of torque.
In nine years on sale, the Raptor has never had any real OEM competition. The first proper challenger the Raptor faces, the Ram Rebel TRX, won't show up until mid-2020 at the earliest. That truck's predicted to get two engine options, the top one with "well in excess of 575 hp." Ford can afford to wait and see how progress develops on the other side of town in Auburn Hills, but if Ram brings a properly sorted suspension, Ford will need to load its charge. We figure Ford has a larger engine in mind for the Raptor, but our guess is that whatever it is, it won't be the 7.3. Tuners like Shelby, Hennessey and PowerPax could have different ideas.
