The Ford Godzilla engine is a family of V8 engines offered by the Ford Motor Company. The engines are intended to replace the Modular V10 engine and the Boss V8 engine in many uses. The engine, first introduced with a displacement of 7.3L was first used with Ford Super Duty trucks starting with the 2020 model year and was later added to the Ford E-Series for the 2021 model year. It is also available as a crate engine.[5] A smaller displacement 6.8L was introduced in 2023. Exterior dimensions are smaller than the 385-series 460 engine, and slightly larger than those of the 351 Windsor engine.[6]

Because the engine uses overhead valves actuated by pushrods, it is smaller than many of the overhead camshaft Ford Modular engines, and can be fitted to older cars.[7]
Ford offers several different ratings of the engines that can prioritize either performance or economy. Performance-oriented tunings are intended as a replacement for the Modular V10 engine, while economy-oriented tunings replace the Boss V8 engine.
The highest current state of tune, offered on the Ford Super Duty (F-250/350/450) pickup trucks, offers 4300NaN0 at 5,500 RPM and 4750NaN0 of torque at 4,000 RPM.
For the largest Super Duty trucks (F-550/600) and the medium-duty Ford F-650/750 trucks, the engine is de-tuned to at 3,750 RPM, but with more torque, at 3,750 RPM.
The E-Series offers two versions that were de-tuned even further. The "premium-rated" version generates and of torque at 3,750 RPM, while the "economy-rated" variant produces and of torque at 3,250 RPM. The "economy-rated" variant was discontinued for 2024.[8]
A short-stroked 6.8L version has been introduced in the revamped 2023 Ford Super Duty as a replacement for the predecessor's 6.2L SOHC Boss V8. It is available only in the F-250 and F-350 pickups with the XL trim.
For 2024, the 6.8L gained flex-fuel capability.
