Ford's 7.3L V-8 Gas Engine: Best-in-Class 430 hp and 475 lb-ft of Torque

Earlier this year, Ford announced a new 7.3L V-8 gasoline engine option for the 2020 Ford Super Duty. Ford foreshadowed best-in-class horsepower and torque from this engine, and indeed has delivered with 430 hp at 5,500 rpm and 475 lb-ft of torque at 4,000 rpm. For reference, the 6.4L Hemi V-8 offered in the 2019 Ram Heavy Duty makes 410 hp at 5,600 rpm and 429 lb-ft of torque at 4,000 rpm, and the new 6.6L V-8 offered in the GM HD trucks churns out 401 hp at 5,200 rpm and 464 lb-ft of torque at 4,000 rpm. Ford's 7.3L engine will be available first in the 2020 Super Duty F-250 and F-350 pickup trucks as an option (along with the 6.7L V-8 Power Stroke) to the standard 6.2L V-8 gasoline engine.
 
"The 7.3-liter is designed for maximum durability in the harshest environments given that our customers live and work in these conditions every day. 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," said Joel Beltramo, Ford manager for gas V-8 engines.

Ford's new engine features an overhead valve architecture that generates power low in the rev range. This helps to get power to the truck to move those heavier loads quicker. The engine also has a variable displacement oil pump, extra-large main bearings, and a durable forged steel crankshaft. Piston cooling jets manage high temperatures under heavy loads.
 
A dyno-certified version of the new 7.3L engine, which will produce 350 hp at 3,900 rpm and 468 lb-ft of torque at 3,900 rpm, will come standard on F-450 chassis cab trucks, F-550, the new F-600, F-650, and F-750 medium duty trucks, and F-53 and F-59 stripped chassis models. Vans join in on the action, with the upgraded E-Series also receiving the new 7.3L V-8 engine. Only the F-250 through F-600 models will have the 10-speed TorqShift automatic transmission; all other commercial models will retain the 6-speed version.
 
As for power, payload, and towing numbers for the third-generation 6.7L Power Stroke? Well, Ford hasn't spilled the beans, but we can anticipate more best-in-class numbers that won't disappoint.
