Ford 7.3L Godzilla Review: Why This Big-Block V8 is Great for Towing and Hauling Campers

I’ll admit it. I used to be one of those diesel snobs.

You know the type. We’d gather around the campfire swapping torque figures like fishermen exaggerating the size of their latest catch. We’d nod knowingly every time someone praised diesel fuel economy, then quietly smirk whenever a gas truck had to wind itself into the stratosphere climbing a mountain pass.

Gasoline engines? Those were for grocery-getters.

Truck campers belonged on diesels. Or so I thought.

Then government-mandated emissions systems entered the chat.

My last diesel—a Cummins 6.7L—taught me a valuable lesson: all the torque in the world doesn’t mean much when your truck suddenly decides it would rather impersonate a riding lawn mower. One faulty DEF component later, I found myself creeping down an Arizona highway at 5 mph while every Prius, Subaru, and overloaded U-Haul blew past me with a mixture of pity and amusement.

Nothing bruises a truck guy’s ego faster than getting passed by a minivan.

That was the day I realized something. Horsepower is great. Torque is wonderful. But neither one means a thing when your truck is sidelined by an emissions sensor the size of a deck of cards.

Reliability suddenly became more important than torque.

So when Ford unveiled the 7.3L “Godzilla,” I did something I never imagined I’d do. I started thinking about a gasoline V8. Not because I stopped loving diesel. Because I got tired of depending on it.

Back to Basics

That’s exactly why the Godzilla caught my attention. While everyone else seemed determined to make engines more complicated, Ford quietly went in the opposite direction.

Instead of asking, “How can we squeeze another 10 horsepower out of this thing?” Ford asked a far better question: “How can we build an engine that owners will still be bragging about 300,000 miles from now?”

The answer wasn’t another turbocharger. It wasn’t direct injection. It wasn’t cylinder deactivation. It wasn’t 47 different sensors waiting for an excuse to illuminate your dashboard like a Las Vegas slot machine.

Instead, Ford dusted off the old-school playbook. Cast-iron block. Forged steel crankshaft. Pushrods. Port fuel injection. One camshaft tucked neatly inside the block where Henry Ford would probably approve.

It’s gloriously old school.

In today’s world of tiny turbocharged engines that resemble Swiss watches assembled by aerospace engineers, the Godzilla feels like someone handed you a Louisville Slugger and said, “Go build something.”

I absolutely love that philosophy. Simple machines tend to be dependable machines.

Numbers Don’t Tell the Whole Story

Truck owners love comparing numbers. Horsepower. Torque. Tow ratings. Gear ratios. It’s the kind of campfire conversation that can last well past bedtime.

But spec sheets don’t haul truck campers. Engines do.

The Godzilla V8 is paired with what may be the best automatic transmission in the heavy-duty truck segment—the exceptional 10-speed TorqShift.

In F-250 and F-350 pickup models, the naturally aspirated V8 produces 430 horsepower and 485 lb-ft of torque.

In F-450 and higher-rated chassis cab models, the engine is calibrated for commercial-duty service, delivering 335 horsepower and 468 lb-ft of torque. While peak horsepower is reduced, the commercial calibration is engineered for durability, reliability, and strong low-end performance under heavy loads.

Those are respectable numbers.

But numbers on paper have never climbed a 6 percent grade with a 5,000-pound camper in the bed while battling a Wyoming crosswind. I wasn’t interested in Ford’s marketing brochure. I wanted to know what this 445-cubic inch V8 would do in real life.

Throwing the Godzilla Into the Deep End

So, I did the unthinkable: I paired Ford’s 7.3L Godzilla V8 with my Elevation Off Grid Black Edition Ford F-550, complete with 41-inch super singles, 4.88 gears, and a LiquidSpring Smart Suspension. It’s probably not the drivetrain combination most people would choose for a truck with an 18,000-pound GVWR—but I wanted to find out how the old school big block would perform in the real world.

Fully loaded, the entire rig tips the scales at 16,320 pounds. Each wheel and tire assembly weighs 195 pounds.

This isn’t a half-ton pickup carrying lawn chairs and a cooler. This is a beast, a heavy-duty expedition vehicle outfitted with a Bowen Customs camper bed and a Kingstar KRUZR 8 camper. If the Godzilla had a weak spot, this was where I’d find it.

Turns out… I underestimated the monster.

The Proving Ground

Every engine review needs a proving ground. Mine came recently on the I-5 outside Grants Pass, Oregon in the middle of a heat wave. If you’ve driven that stretch, you already know what’s waiting.

Long. Steep. Relentless.

The kind of 6-percent grade that separates advertising copy from engineering.

As I reached the bottom of the climb, I settled into seventh gear at 64 mph and buried the throttle. Immediately, the TorqShift transmission went to work.

Seventh. Sixth. Then fifth.

Like a blackjack dealer firing cards across a casino table, it ripped through downshifts with uncanny precision, always keeping the engine exactly where it wanted to be.

Soon the tach settled between 3,500 and 3,800 rpm while the truck maintained between 55 and 60 mph all the way to the summit.

Engine temperatures? Rock solid.

Transmission temperatures? Never flinched.

Here’s where lifelong diesel owners need a small mental adjustment.

Forget everything you’ve learned about low rpm. The Godzilla isn’t screaming at 3,800 rpm. It’s smiling. Unlike a diesel that flexes its muscles at 1,800 rpm, Ford’s big-block likes to stretch its legs. It doesn’t pull like a diesel. It pulls like a classic American V8.

That’s an important distinction.

One isn’t necessarily better than the other. They’re simply different personalities. The diesel quietly goes about its business. The Godzilla lets you know it’s having fun.

And honestly… So was I.

Another Advantage

If you’re interested in hauling a truck camper, here’s another number you should pay close attention to—and it may be even more important than horsepower or torque—payload.

Compared to Ford’s 6.7L Power Stroke diesel, the 7.3L Godzilla V8 weighs roughly 800 pounds less when the diesel’s turbocharger and emissions equipment are also factored in. That significant weight savings translates directly into more available payload capacity, with the exact increase depending on the truck’s configuration.

For truck camper owners, that’s huge.

Those extra pounds can be the difference between carrying a larger camper instead of settling for a smaller one. It means more fresh water, more batteries, more solar, more gear, and more cargo without exceeding your truck’s GVWR.

For many buyers, the Godzilla’s biggest advantage isn’t found under the hood. It’s printed on the tire and loading sticker inside the driver’s door.

A Soundtrack Worth the Price of Admission

Something grabbed my attention the first time I started the 445 V8—the soundtrack.

Modern diesels have become almost appliance-like. Years of emissions equipment have muted them into expensive industrial vacuum cleaners.

The Godzilla couldn’t care less.

Turn the key and you’re greeted by a deep, unmistakable V8 rumble that instantly transports you back to the glory days of Ford’s legendary big-block engines.

It doesn’t whisper. It doesn’t hum. It roars when you hit the peddle.

Neighbors may not appreciate your 0600 departure for elk camp, but that’s okay. They’ll get used to it.

Yes… Godzilla Likes Gas Stations

Now for the elephant standing at the fuel pump. I’m averaging between 8-9 mpg.

No surprises there. A 16,300-pound expedition rig pushing enough wind to qualify as a mobile billboard isn’t exactly designed to hypermile. The 4:88 gears don’t help either.

Would I like better fuel economy? Of course, but 8-9 mpg isn’t bad for a monster rig like ours. By comparison, F-250 and F350 owners with higher (taller) gears and lighter loads fare much better.

But reality has a funny way of crushing dreams. The difference is that every gallon I burn comes without wondering whether my DEF system is planning to ruin my vacation.

I’ll happily buy a little more gasoline in exchange for a less anxiety and stress on our adventures.

With the 40-gallon fuel tank, my practical range falls between 270 and 300 miles since I usually refill around the 1/4-tank mark. Sure, I visit fuel stations more often. But I leave every one of them knowing the engine underneath the hood isn’t plotting against me.

The Godzilla is dependable. Reliable.

Yes, there were camshaft and lifter wear/delamination issues in the 2020 and 2021 model years, but those have been completely resolved by Ford.

Our Godzilla has been flawless.

The Verdict

After 10,000 miles and a year behind the wheel, I’ve come to a conclusion I never thought I’d make. For most truck camper owners, the Ford 7.3L Godzilla isn’t just a viable alternative to diesel—it’s the better choice.

Now, before the diesel faithful flood the comments section, let’s acknowledge the obvious. If you’re hauling or towing 19,000 pounds through the Rockies every week, the 6.7L Power Stroke is still the undisputed heavyweight champion. It delivers more torque, climbs grades with less drama, and rewards you with better fuel economy. That’s exactly what the diesel was built to do, and nothing in this article changes that.

But that’s not how most truck camper owners roll.

Most of us drive F-250s and F-350s carrying campers that put our fully-loaded rigs somewhere between 11,000 and 14,000 pounds. For that mission, the Godzilla doesn’t just hold its own—it shines.

Yes, you’ll sacrifice some torque.

Yes, you’ll visit the fuel pump a little more often.

But in return, you’ll get a truck with a significantly lower purchase price, cheaper fuel, lower maintenance costs, higher payload, and an engine that’s refreshingly simple to own.

There are no turbochargers to worry about. No DEF system. No diesel particulate filter. No regeneration cycles. No expensive high-pressure fuel system. Just a big, naturally aspirated V8 that starts every morning, sounds fantastic, and gets down to business.

Ford didn’t just build another gasoline V8. They built the big-block engine thousands of truck camper owners have been waiting for. It’s powerful enough for nearly every truck camper on the road, remarkably refined, refreshingly uncomplicated, and engineered with the kind of durability that’s becoming increasingly rare in today’s automotive world.

After spending most of my adult life worshipping at the altar of diesel torque, that’s a monster of a revelation.
