In early 2019, Ford revealed its all new Super Duty, and along with it, a new naturally aspirated 7.3-liter pushrod gasoline V-8 engine. What it didn't reveal at the time were any specs. Now, we finally know how capable this new Ford V-8 really is.
Ford says it will sell two versions of its new 7.3-liter V-8. The first will be available as an option on the new Super Duty F-250 and F-350, making 430 horsepower at 5500 RPM and 475 lb-ft of torque at 4000 RPM—both best-in-class numbers. It will join the Super Duty lineup alongside the current single overhead cam 6.2-liter gas V-8 and the new 6.7-liter Power Stroke diesel V-8. Specs on the diesel are yet to be revealed.
The second version of the engine will come as standard equipment on the F-450, F-550, F-600, F-650, and F-750, as well as the F-53 and F-59 stripped chassis models. In this trim, it makes 350 horsepower and 468 lb-ft of torque at 3900 RPM. Ford's long-running E-Series van chassis will also get this engine.
Most of the above models equipped with the new 7.3 will also get a new 10-speed automatic, based on the unit from the F-150. Only a handful of parts from the standard transmission have been retained, with most of the internals being beefed up to handle the extra stress. It's the same length as the outgoing six-speed auto, and only 3.5 pounds heavier. The only variants not receiving this new transmission are the F-650 and the F-750.
Ford says things like pricing, specs for Power Stroke diesel, and towing capacity for the 7.3-liter-equipped Super Duty will be revealed in the near future.
