When Ford announced F-Series Super Duty Tremor pickup truck a few months ago, along came with it was the announcement of an all-new 7.3-liter gasoline engine. Power figures were unavailable at the time, but today Ford has officially announced an output of 430 horsepower at 5,500 rpm and best-in-class torque of 475 lb-ft at 4,000 rpm. That’s 29 more horsepower and 11 lb-ft more than the new 6.6L gasoline V8 engine found in the 2020 Chevrolet Silverado HD and GMC Sierra HD. Meanwhile, the the Ford 7.3L V8 puts out 20 more horses and 46 lb-ft more torque than the 6.4L Hemi V8 in the Ram HD. That makes this high displacement engine is best-in-class of all the 3/4 and full-ton pickup trucks.
Ford will offer its new 7.3L V8 all the way through the lineup from its Super Duty pickups, to its massive Class 7 commercial trucks.
Unlike the 5.0L Coyote V8, which is a DOHC configuration, The new Ford 7.3L V8 is an overhead valve design (pushrod(, which carries superior packaging and power in the low-end rev range, which will pay dividends in the towing and hauling department. It also features a variable-displacement oil pump, extra-large main bearings, forged steel crankshaft for durability, and piston cooling jets to help manage temperatures under heavy load.
The 7.3L will slot above the 6.2-liter V8 gas engine in the Ford Super Duty lineup, capped by the third-generation 6.7-liter Power Stroke diesel V8. Additional power and capability numbers, including Super Duty towing and payload ratings as well as power numbers for the upgraded 6.7-liter Power Stroke diesel will be announced later this year when the trucks launch.
A specially tuned version of the Ford 7.3L V8 will be standard on the F-450 chassis cab, F-550, F-600, F-650, F-750, and F-53/F-59 stripped chassis models. With a greater bias for torque, this version will produce a dyno-certified 350 horsepower at 3,900 rpm and 468 lb-ft of torque at 3,900 rpm. What’s more, the upgraded E-Series will also feature the 7.3-liter V8.
As a cherry on top, Ford will also offer an optional calibration that will offer greater fuel economy for those that need it. More information will be made available at a later date.
The Ford 7.3L V8 engine is paired with the all-new Ford-designed and Ford-built 10-speed heavy-duty TorqShift automatic transmission from the F-250 to the F-600. All other commercial models retain the TorqShift heavy-duty 6-speed automatic transmission.
