The Ford 7.3L Godzilla V8 was introduced in 2020 for the Super Duty lineup and E-Series vans. Unlike modern overhead-cam engines like the Coyote and EcoBoost, the Godzilla is a pushrod big-block V8 designed for simplicity, torque, and durability.
With 430 hp and 475 lb-ft of torque, it’s built for towing and fleet duty. It’s also available as a crate engine for swaps, making it a favorite for hot rodders.
While more reliable than many modern engines, the Godzilla has known issues with oil leaks, valvetrain noise, and tuning quirks.
At DK Auto & Diesel Service in Magnolia, TX, we repair, service, and upgrade Ford Godzilla engines for both fleet work and performance builds.
