The 7.3-liter V8 gasoline engine in the Super Duty pickup cranks out 430 hp at 5,500 rpm and 475 ft.-lb. of torque at 4,000 rpm.
“This engine has the largest displacement in its class and is designed to provide benefits in key areas like power, durability, ease of maintenance and total operating costs,” says Joel Beltramo, Ford manager for gas V8 engines.
The 7.3-liter V8 features an overhead valve architecture that generates power low in the rev range to help get heavier loads moving sooner and with greater confidence. 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 7.3-liter will be available first in Super Duty F-250 and F-350 pickup models. It joins the 6.2-liter V8 gas engine in Super Duty’s lineup, along with the upgraded 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.
A dyno-certified version of the 7.3-liter V8 producing 350 hp at 3,900 rpm and 468 lb.-ft. of torque at 3,900 rpm will be standard on F-450 chassis cab, F-550, the new F-600, F-650 and F-750 Medium Duty trucks, and F-53 and F-59 stripped chassis models. The upgraded E-Series will also feature the 7.3-liter V8. An optional calibration intended to help customers reduce their fuel consumption will also be offered; more information will be made available at a later date.
For F-250 through F-600 models the 7.3-liter engine is paired with the Ford-designed and built 10-speed heavy-duty TorqShift automatic transmission. All other commercial models retain the TorqShift heavy-duty 6-speed automatic transmission.
