DEARBORN – Ford F-Series, America’s best-selling truck for 42 years, is once again raising the bar for capability with its all-new 7.3-liter V8 gasoline engine. The 7.3-liter engine in Super Duty pickup cranks out best-in-class gas V8 output of 430 horsepower at 5,500 rpm and best-in-class torque of 475 ft.-lb. at 4,000 rpm.

No other competitor provides such a powerful and advanced gasoline engine in such a broad range of offerings – from Class 2 Super Duty pickups through Class 7 commercial trucks.

“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,” said Joel Beltramo, Ford manager for gas V8 engines. “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.”

Based on decades of commercial engine experience, the 7.3-liter V8 delivers class-leading performance in a compact package. 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 all-new 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.

The 7.3-liter engine is paired with the all-new Ford-designed and Ford-built 10-speed heavy-duty TorqShift®automatic transmission on all models except F-650 and F-750, which retain the heavy-duty 6-speed.

It is nice to see Ford designing new engines to fit a purpose, instead of modifying existing engines and hoping for the best.

The issue is that a clean sheet design is still only broadly competitive with its competition. That includes torque which GM is only 11 lb ft shy with even less displacement.
I don't think getting the most power & torque out of the 7.3 was the priority. It's a workhorse engine with a focus on durability, low operating cost/maintenance etc.

Indeed, that is exactly what they did, engineer a bespoke and affordable option, with a bigger emphasis on commercial market, whose case study requirements drove the design.

Maybe Ford also got tired of complaints regarding the sheer size of the OHC motors, however capable they may be.

A bit dramatic for humor, perhaps.

Honestly, the 6.2L SOHC is not that much bigger. It's wider, sure, but shorter and about the same height as the 7.3L. The 5.0L is much shorter yet and not as tall as the 7.3L. Appearances can be tricky. The 7.3L will not have a following, like other motors. Pure workhorse that will avoid the limelight.

Kinda humorous, kinda the results of watching some of my tuner shop buddies reminding me how easily LS motors wedge into tighter spaces compared to mod motors. I usually remind them that they require an extra liter of displacement to get a tenth advantage, ask 'em if they miss Vortech rod knock, and wander off.

I am curious how the new motor will respond to the inevitable and imminent modifications/tunings. Check upcoming SEMA shows....
