The Ford 7.3 Godzilla: Is It Reliable? Is It a Good Motor?

Breaking Down the Ford 7.3 Godzilla Engine — Power, Reliability & Real-World Performance

If you’ve spent any time around Ford trucks or performance forums lately, you’ve probably heard the buzz about the 7.3 Godzilla engine. Known for its old-school pushrod design and massive torque, the Ford 7.3 Godzilla has become a favorite among truck owners, hot rodders, and fleet operators alike. But is the 7.3 Godzilla a good engine? And how does it stack up in terms of reliability and specs?

At Mike’s Auto Service in Newington, CT, we work on all kinds of Ford trucks and engines — including the powerful 7.3 Godzilla motor — so here’s everything you need to know before you buy, swap, or service one.

What Is the Ford 7.3 Godzilla Engine?

Introduced in 2020, the 7.3 Godzilla engine was Ford’s answer to modern V8 demands — a naturally aspirated, large-displacement gas engine designed for the Super Duty lineup (F-250, F-350, F-450) and other heavy-duty applications.

Unlike the smaller EcoBoost or the diesel Power Stroke options, the Godzilla 7.3 brings back a traditional pushrod design, prioritizing simplicity, low-end torque, and long-term durability over high-tech complexity.

Is the 7.3 Godzilla Reliable?

In a word: yes. The Ford 7.3 Godzilla is quickly proving itself to be one of the most reliable modern V8s on the market.

• Simplicity: The pushrod design reduces moving parts and complexity — fewer things to break compared to overhead cam systems.
• Heavy-Duty Components: With a cast-iron block, forged crankshaft, and oil-cooled pistons, it’s engineered for endurance.
• Serviceability: Mechanics love the 7.3 because it’s easy to work on. No complicated timing chains or twin-turbo setups.

Common 7.3 Godzilla Issues (and How to Prevent Them)

• Oil leaks from valve covers or oil pans due to gasket wear
• Exhaust manifold bolts that may loosen over time
• PCV valve issues leading to rough idle or minor oil consumption

These are all relatively minor problems and easily fixed — especially with regular oil changes, inspections, and quality service from a trusted shop like Mike’s Auto Service.

Is the 7.3 Godzilla a Good Engine?

Absolutely. The Ford 7.3 Godzilla has earned its reputation as a dependable, durable, and high-torque powerhouse.

• Excellent for towing and hauling heavy loads
• Great fuel economy (for its size) compared to older big-block V8s
• Ideal for engine swaps in classic cars, hot rods, and off-road rigs
• No turbo lag or complex electronics — just raw, mechanical performance

In short, the 7.3 Godzilla engine combines modern reliability with old-school toughness — making it one of the best gas engines Ford has produced in decades.
