I kept spotting photos of this truck online that always seemed to take me to a Pinterest post with no information. Intrigued, I set out to find more photos and information on it. I eventually came up with a name, and that lead me to a facebook page.
The 1977 Ford F-150 you see here is owned by Rob Terhaar of Dyna-Fab Offroad from Molalla, Oregon.
The truck is powered by a 460 CID big block with Holley injection. The transfer case is outfitted with a Northwest Fabworks (NWF) BlackBox reduction box with cable shifters for more low end grunt.
The truck uses a 4-link suspension and coilovers, and currently rides on AxleTech planetary axles with front and rear steering. Prior to the AxleTech axles, the truck was running on a Dana 60 front, and a shaved GM 14-bolt rear with disc brakes and chromoly axles.
Tire wise, the truck has ran 44-inch Pitbull’s, moved up to 49-inch Iroks, and then finally to 54-inch Mickey Thompson Baja Claws (after the planetary axle upgrade).
The trucks nose (hood, fenders, grill, etc) were narrowed, and the bed was narrowed to match.

Just how big is a 54-inch tire?

How much does it snow in Oregon? Remember, those are 54-inch tires.

About The Author
Growing up, my father always believed that every family needed a truck—there’s just something about having a vehicle capable of hauling anything at a moment’s notice. That philosophy stuck with me, and it’s been the foundation of my lifelong passion for Ford trucks.
While I’m best known for my work with Ford Rangers, I’ve owned a wide variety of Ford trucks over the years—including F-150s, F-250s, F-350s, and even larger rigs like the Ford Excursion, Ford Expedition, and a 1982 Ford Econoline Sportsmobile camper van. I’ve used these vehicles for everything from family transportation to towing car trailers and campers, and each one has fueled my love for Ford’s versatility and durability.
I especially enjoy the styling of 1970s and 1980s Ford trucks—the bold designs, rugged presence, and classic charm are timeless. Sharing my passion for Ford trucks, vans, and SUVs with other enthusiasts online brings me a great deal of joy, and it’s why I created Blue Oval Trucks.
This website is dedicated to helping Ford truck enthusiasts explore, learn about, and celebrate these incredible vehicles. While I share my expertise and experiences here, Blue Oval Trucks is an independent enthusiast site and is not affiliated with Ford Motor Company.
