Decades after the production of the 7.3L Powerstroke V8 Diesel engine, one of the most sought-out Diesel engines ever produced, Ford brought back a 7.3 Liter Displacement Engine. It’s not a diesel, but it’s an impressive V8 engine that cranks out a whopping 430 horsepower and 475 ft.-lb of torque. Ford’s 7.3L V8 “Godzilla” Gasoline engine offers impressive specs and is available in pretty much the entire Heavy-Duty Ford Line-up, from the Ford F-250 to the F-750 and is also on the E-Series Work Vans. It’s more capable than the standard 6.2L V8 Engine that is the standard powertrain on Superduty pickup trucks. It’s not just more capable, however, it also features a number of unique design elements that make it more robust and dependable.
In this post, our guide to the Ford 7.3L V8 Godzilla Gas Engine, we’re going to cover this engine’s specs, design information, and performance data. We’ll also mention the differences between this engine and the 6.2L V8 engine that is also available in both Superduty trucks and the E-Series Vans.

Ford 7.3L V8 “Godzilla” Engine Key Design Elements
Ford’s 7.3L V8 Gas Engine checks all the boxes when it comes to a commercial vehicle powertrain. It’s durable, dependable, powerful, and easy to maintain. Despite being the largest displacement gas powertrain available in the Ford’s Line-up, it also is relatively small, allowing it to be placed in even the E-series vans. It’s also extremely versatile. E-Series customers are able to get a gaseous fuel prep package that comes with upgraded valvetrain components to support the higher operating temperatures and reduced lubricity of fuels such as CNG or Propane. Flex fuel options are also available to customers seeking a more cost-efficient fuel type.
Here is some insight into what makes the Ford 7.3L “Godzilla” V8 Engine so capable, versatile, and durable.
7.3L V8 Engine Composition/Construction
Ford’s 7.3L V8 Godzilla Engine is a pushrod style V8 engine that utilizes a cast-iron block with a cam-in-block and OHV (overhead Valve) architecture. The In-Block Cam design helps reduce both engine height and width. Four bolt and cross bolted main bearings provides optimal strength and stiffness for improved longevity and durability. A forged steel crankshaft is also used, furthering strength and durability.
For even greater durability, the 7.3L V8 Gasoline Engine contains robust pistons and ring packs containing anti-wear coatings. Piston cooling jets help create even greater longevity and maintain combustion efficiency. A variable displacement oil pump found in the pan increases oil flow when required and ensures engine lubrication in all conditions. It even accounts for changes due to engine wear, helping to provide consistent performance as the engine gets older and more worn.
New heads with port fuel injection provide maintenance simplicity, yet high air flow. Variable-Valve timing optimizes the intake and exhaust for maximum performance.
Ford 7.3L V8 Godzilla Gasoline Engine Performance
Ford’s 7.3L V8 Engine is extremely versatile, making it a powertrain that is available in a wide range of heavy-duty applications. It’s found predominantly in Ford’s Superduty pickup trucks from the F-250 to the F-600, but it’s also available in the E-Series in two different variants. In Ford F-250-F-600 trucks, it’s partnered with the 10-speed Torqshift Automatic Transmission. Other commercial models use the heavy-duty 6-speed Torqshift transmission.
The original iteration of the 7.3L Godzilla V8 engine cranks out 430 Horsepower and 475 lb.-ft of torque when found in the Ford F-250 or Ford F-350. In the 2023 model year, power numbers were slightly increased, resulting in these and newer trucks having 430 horsepower and 485 lb.-ft of torque. These numbers are much higher than the 6.2L V8 Gasoline Engine which was the standard engine on Ford Superduty trucks until the 2023 model year. In 2023, the 6.2L V8 engine was replaced with a new 6.8L V8 Gasoline Engine which made the margin tighter, but doesn’t edge out the 7.3L V8 in horsepower or torque. Despite holding the crown in the gasoline engine category, the 7.3L V8 Engine has less than half the torque of the 6.7L Powerstroke V8 Diesel engine, the recommended powertrain choice for frequent towing.
Despite having lower performance figures than the Powerstroke, Ford’s 7.3L V8 Godzilla Gasoline-powered engine should strongly be considered in commercial and fleet applications where you’re not towing as heavy of loads or as frequently. 7.3L V8 Engine Maintenance is simpler and less expensive than the 6.7L Powerstroke and they still provide plenty of power and capability to get the job done.
Ford 7.3L V8 Godzilla Gas Crate Engines
Commercial Customers aren’t the only one who can benefit from the 7.3L V8 Gas Engine. Ford made the 7.3L Godzilla Engine available as a crate engine. Many believe this to be a sign that this engine is significantly detuned from the factory and capable of sustaining much higher performance figures. If you’re looking for a complete engine to drop-in to your custom build, you should definitely consider the Ford 7.3L Godzilla Gas Engine due to its impressive performance specs and durability.
Ford Superduty 7.3L V8 Godzilla Engine Performance Upgrades
You don’t have to purchase a crate engine or build a custom track vehicle to benefit from the ease at which you can modify the 7.3L V8 Engine. Many truck owners seek improved performance from their daily driving vehicles or tow rigs and these trucks with these engines can be easily upgraded. Check out our Ford Superduty 7.3L V8 Godzilla Performance Upgrades Post for some ideas on how to improve the horsepower and torque on your 7.3L-Equipped Ford Superduty.
Ford 7.3L V8 Gas Engine Variations
Ford’s 7.3L V8 Gasoline Engine features multiple configurations that are available through-out Ford’s different vehicles. The higher-output 7.3L V8 engine is available in exclusively Ford F-250 and F-350 Superduty pickup trucks. Cab & Chassis, E-Series Vans and Fleet/Commercial Variations like the F-750 utilize a de-tuned engine that provides lesser output with the goal of longer longevity. 2022 and newer Ford E-series Vans actually offer two different 7.3L V8 options, a premium version offering higher performance specs, and an economy-centric model, offering greater fuel economy and lower performance figures.
Here is a snapshot of the spec differences between Superduty Models vs Commercial Models.
| Specs | Superduty (F-250 & F-350) | Premium (Standard Commercial 7.3L V8) (F-450-750 & E-Series) | Economy 7.3L V8 |
| Horsepower | 430 HP @ 5,500 Rpm | 350 HP @ 3,900 rpm | 300 @ 3,750 rpm |
| Torque 2020-2022 2023 | See Below 475 lb.-ft @ 4,000 Rpm 485 lb.-ft | 468 lb.-ft. @ 3,900 rpm | 425 lb.-ft. @ 3,250 rpm |
Ford E-Series 7.3L V8 Engine Information
The Ford E-series is a staple amongst service companies and other types of contractors and Ford knows that these vehicles are used differently. They created two different engine calibrations with different power levels to help commercial customers. The premium E-Series 7.3L V8 engine has 350 horsepower and 468 lb.-ft of torque. The Economy 7.3L V8 engine has 300 horsepower and 425 lb.-ft of torque.
Both of these engine calibrations have available flex fuel capabilities, meaning they can run on gasoline or blends of up to 85 percent ethanol (E85). Ford even offers a gaseous fuel prep package for these trucks, allowing them to run on CNG or Propane. The gaseous prep package features upgraded valvetrain components that allow the 7.3L engine to endure higher operating temperatures and the lesser lubricity of these types of fuel.
