EVEN ’GLASS IS SCARCE
For 1933, Dodge had a full line of automobiles, and the salesmen of the day no doubt touted that there was a Dodge model perfect for you. But of all the sedans, coupes, convertible sedans (of which only 13 four-door convertible sedan eight-cylinder models were built) and station wagons, the convertible coupe was no doubt the most stylish of the bunch. The ’33 Dodge convertible coupe was a rare car in 1933, with only 1,563 units being produced, and, of course, there were 56 more built with the eight-cylinder engine. So, while the convertible coupe was a strikingly good-looking automobile, it was not the best of times, and the practicality and affordability of coupes and sedans far outsold the convertibles of the time. Today, finding a ’33 Dodge convertible coupe is truly a challenge.
TENNESSEE HUMMIN’
It’s long been stated, “If a tree falls in the forest, and nobody here’s it, did it make any noise?” which offers up another question. If the beauty of a forest is out of reach and remains unseen, is it ever to be appreciated?
Hot Rods Dirt Cheap
Jack Fuller has been at this hot rod game for a long time, and while he builds hot rods for a living, make no mistake—this is a man who loves his work. As a matter of fact, the mantra of the garage is, “When the fun stops, the doors close for good.” It’s pretty simple stuff, and oddly enough, that seems to be the specialty of the house—basic hot rods that look cool and work well. Jump in a Jack Fuller hot rod, and you’ll know it was designed to be driven. Jack’s own ’32 cabriolet has seen untold miles over the years, as have most of the other hot rods he has built.

PRODUCT SPOTLIGHT: ARP’s Head Stud Kit for 1927–31 Ford Model A 4-Cylinder Engines
ARP Brings Modern Engineering to Vintage Ford Engines

In a world obsessed with the latest engines and newest technology, ARP (Automotive Racing Products) just proved something important—progress doesn’t only move forward. It also means going back and applying everything we’ve learned since.
This time, that focus lands on one of the most iconic engines ever built: the 1927–31 Ford Model A four-cylinder.
100 Years of Progress Later
The Ford Model A engine was engineered in a time when simplicity and durability mattered above all else. It wasn’t overbuilt, and it didn’t need to be. It was designed to work—and nearly a century later, the fact that these engines are still running says everything about how right Ford got it.
What’s changed isn’t the engine—it’s everything around it.
A hundred years of advancements in metallurgy, machining, and engine engineering have redefined what’s possible in strength, consistency, and long-term durability. Today, we understand how materials behave under heat, load, and time in ways that simply didn’t exist when the Model A engine first rolled off the line.
That doesn’t change what made the design great—it just means we can now back it up with better materials and smarter engineering.
Modern Engineering Steps In
The ARP head stud kit for the Model A is a direct reflection of that progress. Manufactured entirely in-house at ARP’s California facilities, each stud is produced from premium-grade 8740 chrome moly steel with a nominal tensile strength around 190,000 psi—making it significantly stronger than the original Model A hardware these engines relied on.
These aren’t just material upgrades—they’re process-driven improvements. Threads are rolled after heat treatment, a critical step that increases fatigue strength up to 20 times compared to conventional methods. It’s the same level of engineering ARP applies in professional motorsports and high-performance engine builds, now brought back to a vintage Ford platform.
Every component—from the studs themselves to the hardened washers and polished stainless acorn nuts—is designed to deliver consistent clamping force and repeatable installation. It’s not about changing what makes the Model A great—it’s about making proven, reliable technology even better with everything we’ve learned since.

Why Builders Will Notice the Difference
Anyone who has worked on a Model A engine knows the value of doing things right the first time. Clean surfaces, proper torque, and careful assembly all matter—but the consistency of the hardware plays a bigger role than most realize.
What ARP fasteners bring to the table is control.
More consistent torque retention. Improved head gasket sealing. Hardware that holds through heat cycles instead of slowly relaxing over time. It’s the kind of upgrade that doesn’t change how the engine looks—but absolutely changes how it performs and survives.
Built for the Way Cars Are Driven Today
Model A engines aren’t just sitting in collections—they’re being driven, modified, and pushed in ways their original engineers never had to consider. Longer trips, higher sustained speeds, and modern traffic all demand more from the platform.
Upgrading to ARP head studs isn’t about chasing performance numbers—it’s about ensuring the engine stays together and performs consistently, mile after mile, without compromise.
The Bottom Line
The Ford Model A helped lay the foundation for everything hot rodding would become. That hasn’t changed.
What has changed is what we’re capable of doing with it.
The ARP Model A head stud kit doesn’t rewrite history—it builds on it—using a century of progress to make a great engine even better.
Ready To Upgrade?
Don’t settle for stock hardware. Give your Model A the ARP advantage—stronger, tighter, built to last.
