Ford Mustang May Pack Pushrod Power from 2020 Super Duty

2020 Ford Super Duty 7.3-Liter V8

New 7.3-liter Super Duty engine could bring about the return of the big block Ford Mustang—but it’s a long shot.

When Ford introduced the 2020 Super Duty, the biggest change compared to the current models is the availability of an all-new 7.3-liter gasoline V8. Unlike all of Ford’s other V8 engines over the past 20 years or so, this new mill has pushrods rather than an overhead camshaft design and with this old school engine technology, the Motor Company expects to have the most powerful gasoline engine in the heavy duty segment. However, this engine could have other applications in the future, including the F-150 and even the Mustang.

While speaking with Ford spokesman Mike Levine, Motor Authority learned that the new 7.3-liter V8 will fit in the engine bay of the current F-150 and the S550 Mustang. It was pointed out that this new engine has an iron block, so it is too heavy for the pony car, but with a lightweight engine block, this new Super Duty engine could lead to the biggest V8 that ever powered the mighty Mustang.

Biggest Mustang Engine Ever

The biggest engine ever offered from the factory in a Ford Mustang was the 429-cubic inch, 7.0-liter Cobra Jet V8 that was discontinued after the 1971 model year. There was also a 428-cubic inch Cobra Jet engine, but since 1971, the biggest Mustang engines have been a few different 5.8-liter mills, with the 2014 GT500 being the last model to come with an engine that big.

Of course, the volume V8 engines in the Mustang dating back to the 1980s has been either a 4.6- or 5.0-liter V8, but if Ford adapts the new Super Duty 7.3-liter engine to make sense in the pony car, it will be the biggest engine to ever grace the model’s lineup.

7.3-Liter Power

Unfortunately, we don’t know how much power the 7.3-liter V8 will offer in the 2020 Super Duty, but we know that Ford has promised that it will be the most powerful gasoline engine in the segment, topping the 6.4-liter Hemi in the Ram lineup. That V8 delivers 410 horsepower and 429 lb-ft of torque and with the current Ford 6.2-liter Super Duty engine offering 385 horsepower and 430 lb-ft of torque, the Motor Company should have no problems beating Ram’s numbers with all of that displacement.

Now, say that the Super Duty 7.3-liter V8 offers similar volumetric efficiency to the 6.2. That would lead to numbers of roughly 455 horsepower and 510 lb-ft of torque. Based on the 6.2-liter V8 that was used in the previous generation of the Raptor, an F-150 variant of the 7.3-liter mill would offer lots more horsepower and a touch more torque. Figures of 500 horsepower and 515 lb-ft of torque seem realistic for an F-150 version of the 7.3 and if you look at the comparison of the 5.-liter engine in the Mustang GT and the F-150, there is a similar jump to that seen between the two 6.2-liter truck engines.

The F-150 6.2-liter V8 is tuned to offer a bit more power on the top end compared to the Super Duty version, which offers more working ability with a flatter torque curve and earlier peak torque. The same is true of the 5.0-liter engines, with the Mustang GT engine being tuned to make big power on the top end while, by comparison, the  F-150 5.0 is tuned to make ideal power for pulling a heavy load. With this in mind, an F-150 7.3-liter engine with 500 horsepower and 515 lb-ft of torque that has been modified similarly to the 5.0-liter V8 could see horsepower climb up around 500 while torque would likely settle into the area of 500 lb-ft.

Need for Green Ford Mustang GT

The only downside to this idea is that a naturally aspirated, 7.3-liter Mustang engine would be horribly inefficient in terms of fuel economy, but if Ford made this engine part of some low-production package, it would give buyers the chance to score the closest thing to a modern big block Mustang that we will ever see.

A lifetime automotive expert, diehard Dodge fan, and respected auto journalist for over 10 years, Patrick Rall is highly experienced in the automotive world. He has clocked in time as an auto mechanic, longtime drag racer and now auto journalist who contributes to nearly a dozen popular websites dedicated to fellow enthusiasts.

“Before I was old enough to walk, my dad was taking me to various types of racing events, from local drag racing to the Daytona 500,” says Rall. “He owned a repair shop and had a variety of performance cars when I was young, but by the time I was 16, he was ready to build me my first drag car: a 1983 Dodge Mirada that ran low 12s. I spent 10 years traveling around the country, racing with my dad by my side. While we live in different areas of the country, my dad still drag races at 80 years old in the car that he built when I was 16. Meanwhile, I race other vehicles, including my 2017 Dodge Challenger SRT Hellcat and my 1972 Dodge Demon 340.

“Although I went to college for accounting, my time in my dad’s shop growing up allowed me the knowledge to spend time working as a mechanic before getting my accounting degree, at which point I worked in the office of a dealership group,” adds Rall. “While I was working in the accounting world, I continued racing and taking pictures of cars at the track. Over time, I began showing off those pictures online and that led to my writing.

“Ten years ago, I left the accounting world to become a full-time automotive writer and I am living proof that if you love what you do, you will never ‘work’ a day in your life. I love covering the automotive industry and everything involved with the job. I was fortunate to turn my love of the automotive world into a hobby that led to an exciting career, with my past of working as a mechanic and as an accountant in the automotive world provides me with a unique perspective of the industry.

“My experience drag racing for more than 20 years coupled with a newfound interest in road racing over the past decade allows me to push performance cars to their limit, while my role as a horse stable manager gives me vast experience towing and hauling with all of the newest trucks on the market today.

“Being based on Detroit, I never miss the North American International Auto Show, the Woodward Dream Cruise and Roadkill Nights, along with spending plenty of time raising hell on Detroit’s Woodward Avenue with the best muscle car crowd in the world.”
