| Predecessor | Ford 385 engine Modular V10[1][3] Ford Boss engine |
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.[1][3] 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.[3][4] 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]
Attributes[edit]
- Camshaft: Variable valve timing
- Piston: Hypereutectic aluminum alloy
- Connecting rod: Cracked powdered metal
- Crankshaft: Forged
- Knock sensors from the Ford Boss engine
- Siamesed cylinders with saw cuts between cylinders to increase cooling capacity
- Variable oil pump for fuel economy[7]
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]
Variable tuning[edit]
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 430 horsepower (321 kW) at 5,500 RPM and 475 pound-feet (644 N⋅m) of torque at 4,000 RPM.[3]
For the largest Super Duty trucks (F-550/600) and the medium-duty Ford F-650/750 trucks, the engine is de-tuned to 335 hp (250 kW) at 3,750 RPM, but with more torque, 468 lb⋅ft (635 N⋅m) at 3,750 RPM.[4]
The E-Series offers two versions that were de-tuned even further. The "premium-rated" version generates 325 hp (242 kW) and 450 lb⋅ft (610 N⋅m) of torque at 3,750 RPM, while the "economy-rated" variant produces 300 hp (224 kW) and 425 lb⋅ft (576 N⋅m) of torque at 3,250 RPM. The "economy-rated" variant was discontinued for 2024.[8]
6.8L variant[edit]
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.
