New Ford 7.3 V8

If you mean like the "FE" series or "385" or even the "Triton" series, I don't think it's even close to those.. Here is a quick Google lookup right from the Ford.com site.

All-new 7.3-liter engine in Super Duty pickup cranks out best-in-class gas V8 output of 430 horsepower and best-in-class gas torque of 475 ft.-lb.
The 7.3-liter engine is paired with the all-new 10-speed heavy-duty TorqShift® transmission on Super Duty pickups and is designed for robust power, long-term durability and ease of service that truck owners demand in both personal and business applications
Windsor-built engine will be an option on 2020 F-Series Super Duty pickup, standard on F-550, F-600, F-650 and F-750 Medium Duty trucks and E-Series, as well as F-53 and F-59 stripped chassis


DEARBORN, Mich., Aug. 1, 2019 – 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.

A dyno-certified version of the 7.3-liter V8 producing 350 horsepower 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 all-new Ford-designed and Ford-built 10-speed heavy-duty TorqShift® automatic transmission. All other commercial models retain the TorqShift® heavy-duty 6-speed automatic transmission.

Even though it’s a 7.3L I believe the physical dime soon are smaller than the old school big block and even the old V-10.

The real difference is going to be the lower, broader power band coupled with the new 10 speed auto and some other features such as blind spot monitoring, lane keep assist (I think) and adaptive cruise control.

So would a turbocharged 7.3 (maybe Eco isn’t quite accurate) be a sweet engine or what?

Say 650 torques at 2500rpm 450hp at 3900rpm about 400 torques at 1600rpm in road gear on the freeway.

I do not get this throw back to the good old days when we had mouse motors and rat motors and little blocks and big blocks. Personally i think that those terms have gone out of style with grannie's high button shoes.

I think modern day motors are what their displacement is. :h

A turbo big block 7.3 would require a huge fuel tank, a big fuel line, and some big radiators. The owner would need deep pockets. All that being said, I think my next truck will be a 7.3 f-350. I can’t wait to see one go up the Ike!

I agree. It’s why I was wondering why it is being called a “big” block...

I fail to understand your logic. Back in the day some trucks where sold with the same displacement diesel with and without turbos. Over time, and really a short time, the non-turbo was pretty much gone because of more power and better fuel mileage.
And doesn't Ford advertise their smaller turbo/gas engines as "Econo"?

Diesel is a bit of a different animal, although it's a misnomer that the turbo engines get better mileage. Some of the early non turbo diesel pickups could get well over 20 mpg on the highway, but they had no power.

Yes, Ford does brand their gas turbo engines as "Eco", but they really don't get significantly better mileage than N/A gas engines of similar power. Towing, they burn just as much fuel. A 7.3 turbo would probably be overkill. I could see an "Eco" engine of maybe 4.5-5 liters, but engineering one that can handle the same towing duty cycle as the new 7.3 gas or other large gas pickup engines hasn't been figured out yet.

LOL. I have a real good understanding of this. I remember the last day I pulled out of the quarry grossing 110,000, with spark plug motor and the first trip with the same load and diesel.

Don't know much about diesel pickups. Back in the day I was driving gas, most others diesel. Of the hands that had twice the displacement of mine, the N/A ones would load behind me all day, but the turbos would pass. And later, I was paying to feed one of each doing the same work.

But just as much does not imply the need to own a gas station.

A 7.3 turbo would probably be overkill.

But a lot of Tim Allens out there...

Had an
11 5.0 V8 N/A regular driving it got 14mpg towing 8.2 if I was lucky after 6 months of that **** traded it in on a

11 3.5 eco regular driving it gets 16mpg towing it gets 10mpg

18 3.5 eco regular driving 17.6mpg towing it gets 10.7mpg

I would say the 3.5 eco does significantly better than the N/A engine everyday anyday :D


Prior to that had a 08 350 dually that pulled a 14k 5th wheel that got 14mpg regular driving and 8.5mpgs towing the 5th
