Arclight Fab Puts Together an Original and Powerful Unibody

It seems that a lot of stories that truck guys tell follow a similar narrative. They start out as a mini-trucker, building a ride or two along the way. Then they get married, maybe have kids, and when their priorities shift, they stop building for a bit. Once the kids are in school and the cash is flowing more smoothly, they get back up on the horse and start building again. All of that applies to Jonathan Mansour of Rowlett, Texas, with one big difference: television.

It’s not often that a former mini-trucker finds himself on TV, but that’s exactly what happened to Jonathan. As an employee of Gas Monkey Garage and long-time friend of Aaron Kaufman, he found himself on “Fast ‘N Loud,” which would be a surreal experience for anyone. When circumstances shifted and Aaron opened up Arclight Fabrication, Jonathan went with him, bringing his expertise in marketing to the new venture. With a fresh slate and new opportunities, he wanted to build something that would bring him back into the scene and help out the shop. Fortunately, he already owned it.

THE T-5 MANUAL TRANSMISSION CAME OUT OF A FOX-BODY MUSTANG, WHICH KEPT COSTS DOWN AND PUSHES POWER TO THE PAVEMENT.
EVERYTHING ON THE TRUCK IS AS ORIGINAL AS POSSIBLE, WITH THE EXCEPTION OF THE GO-FAST AND COMFORT GOODIES.

Jonathan has always loved unibody Fords, but they can be difficult to find. He spent years combing Craigslist and other online listing sites trying to find the perfect specimen before the right one popped up. In an interesting twist, it was only 4 miles away from his home.

Once the kids are in school and the cash is flowing more smoothly, they get back up on the horse and start building again.”

It was a ’62 Ford F-100 Unibody that had been purchased brand new off the lot and never touched. With the exception of a paint job in the ’80s to freshen up the finish, the truck was just driven and enjoyed for close to 40 years by the original owners, who then sold it to Jonathan. At the time, he was close to done with his ’98 Ford Ranger, and he wanted to move on to something else. But when the kids came, it was like a vacuum siphoned away his spending money, and the truck sat in his garage for around five years, never moving an inch.

THAT 302 V-8 CAME OUT OF AARON’S FALCON, AND—AS A COMPLETE SURPRISE—IT HAD BEEN FRESHLY REBUILT BY THE PREVIOUS OWNER.

Eventually, Jonathan got tired of waiting, and he and Aaron started on Phase 1 of the build, which focused on getting the thing running relatively reliably, and bringing it down to the ground a bit. They installed a Nostalgia Sid’s drop axle paired with a mono-leaf. Aaron made a flip kit for the rear, and they left the drivetrain as-is. For 18 months that worked pretty well, but eventually the drum brakes and iffy motor became too much for Jonathan to deal with, so they decided to move on to Phase 2.

THE WHITEWALLS AND 15-INCH US MAG WHEELS PAIR NICELY ON THIS CLEAN UNIBODY.
IT MIGHT HAVE SAT FOR YEARS, BUT NOW SITTING IN IT IS QUITE THE COMFORTABLE EXPERIENCE.

This time around it was all about power, both moving forward and stopping. The brakes were upgraded to disc with a CPP brake booster and master cylinder. Then the motor was swapped out for a Ford 302 that originally lived in Aaron’s Falcon and only had a few miles on it after its rebuild. Paired with a five-speed instead of the ancient three-on-the-tree manual, he had the ability to put the power to the pavement reliably and smoothly. It’s how the truck sits today, and it looks great.

Of course, there is a Phase 3 in the works. One of the plans over at Arclight is to build parts for 1957-79 Ford trucks, particularly a full chassis kit for each model. One of the first that they’re going to build will sit underneath Jonathan’s unibody, and even though it’s going to be tight, the plan is to get both his and Aaron’s trucks done for LST in 2018. It’s a lofty goal for a new shop, particularly one that’s now going to have its own TV show. But if there’s anybody that can do it, the team at Arclight Fabrication can certainly pull it off.

It seems that a lot of stories that truck guys tell follow a similar path, but they never end quite the same way. Jonathan and his ’62 have a bright future and some lofty goals to hit. If there’s one thing that’s sure, you can bet it’s going to be a fun ride.

What were the production changes made to the F-100 during its early years?

Production Changes to the F-100 During Its Early Years

  1. Fourth Generation Launch (1961)

The fourth generation of the F-series trucks kicked off in 1961, marking the first significant redesign since 1953. This model introduced the “integrated-body” design, commonly referred to as the “unibody” truck. Unlike conventional trucks, the bed was not a separate part but merged into a single metal unit with the cab. This “unibody” construction increased cargo space and streamlined production costs by reducing the need for separate body panels.

  1. Unibody Challenges

However, the unibody design faced substantial issues. Stories began circulating about doors jamming when the truck was loaded and, worse, popping open when crossing rough terrain like railroad tracks. This body flex problem, exacerbated by rust over time, rendered the design unsuitable for heavy-duty tasks.

  1. Mid-Cycle Revision (1962)

Due to these problems, 1962 saw Ford making swift changes. They started producing conventional-bodied half-ton and three-quarter-ton trucks mid-year. These new trucks utilized the box from the 1960 models, which didn’t align perfectly with the 1961 body lines but addressed the critical structural issues.

  1. Transition and Dual Offerings (1963)

By 1963, Ford sold both the unibody and new conventional models side-by-side. The traditional body-on-frame models quickly became more popular, outselling the unibody versions by a margin of two-to-one. These conventional trucks retained the visual appeal but were more robust and practical, meeting the demands of users who needed a reliable work vehicle.

Conclusion

The F-100’s early production years were marked by a notable shift from an innovative but flawed unibody design back to a more traditional and reliable construction. These changes reflected the market’s need for durability and utility over aesthetic innovation.

Why did Ford decide to use an integrated-body design for the 1961 F-100?

Ford decided to adopt an integrated-body design for the 1961 F-100 primarily to streamline manufacturing and cut costs. By combining the bed and body into a single unit, they minimized the need for separate tooling and production steps associated with building multiple body panels.

This shift not only reduced manufacturing expenses but also allowed Ford to create a more spacious cargo area. The unified design provided a practical advantage in terms of increased cargo capacity, which was a significant selling point for customers relying on their trucks for heavy-duty tasks.

Additionally, this design distinguished the 1961 F-100 from competitors by offering a unique structural integrity and durability, further enhancing its appeal in the marketplace.

 

How did Ford respond to the problems with the F-100’s unibody design?

In response to the challenges posed by the F-100’s unibody design, Ford took several significant actions. The unibody construction, despite its appealing aesthetics and urban utility, failed to meet the rigorous demands expected from a truck. Owners anticipated a vehicle capable of enduring hard labor, but the unibody design didn’t quite measure up.

Recognizing this mismatch, Ford pivoted swiftly. By mid-1962, they began producing conventional-bodied half-ton and 3/4-ton trucks. These new models, though hastily assembled, featured the box from the 1960 series, despite some misalignment with the 1961 body lines. This transition was crucial in addressing the durability concerns voiced by their customer base.

The unibody trucks continued production albeit with diminishing popularity. By the end of 1963, these trucks were sold alongside the conventional models. The market clearly preferred the traditional design, as evidenced by the conventional models outselling the unibody trucks two-to-one. This shift underscored Ford’s commitment to adapting their designs in response to customer feedback and practical utility requirements.

 

What is the history and unique features of the 1961 Ford F-100 Unibody?

It was a ’62 Ford F-100 Unibody that had been purchased brand new off the lot and never touched. With the exception of a paint job in the ’80s to freshen up the finish, the truck was just driven and enjoyed for close to 40 years by the original owners, who then sold it to Jonathan.

But what makes the 1961 Ford F-100 Unibody truly fascinating is its place in automotive history. This model marked the beginning of the F-series’ fourth generation and was the first significant redesign since 1953. The term “unibody” is a bit misleading here; technically, it was an “integrated-body” truck. Unlike traditional trucks with separate cab and bed structures, this design featured a continuous piece of metal from the cab to the bed, set upon a traditional body-on-frame chassis.

Unique Features and Market Impact

Challenges and Decline

Despite its innovative design, the “unibody” F-100 faced significant issues. Owners reported problems with doors jamming when the truck was loaded and even popping open while crossing uneven terrain. This body flex was unacceptable for a utility vehicle, leading to a decline in its popularity. By mid-1962, Ford began producing conventional-bodied trucks again, eventually phasing out the “unibody” by the end of 1963.

In summary, while the ’62 Ford F-100 Unibody owned by Jonathan has its charm and historical value, it also represents a bold but flawed chapter in truck design. This model’s story reflects both the innovation and the practical challenges faced by automotive engineers of the era.

 

What modifications and upgrades have been made to the Arclight-built 1961 Ford F-100?

Eventually, Jonathan got tired of waiting, and he and Aaron started on Phase 1 of the build, which focused on getting the thing running relatively reliably and bringing it down to the ground a bit. They installed a Nostalgia Sid’sdrop axle paired with a mono-leaf. Aaron made a flip kit for the rear, and they left the drivetrain as-is. For 18 months that worked pretty well, but eventually, the drum brakes and iffy motor became too much for Jonathan to deal with, so they decided to move on to Phase 2.

This time around it was all about power, both moving forward and stopping. The brakes were upgraded to disc with a CPP brake booster and master cylinder. Then the motor was swapped out for a Ford 302 that originally lived in Aaron’s Falcon and only had a few miles on it after its rebuild. Paired with a five-speed instead of the ancient three-on-the-tree manual, he had the ability to put the power to the pavement reliably and smoothly. It’s how the truck sits today, and it looks great.

Suspension and Brakes

A full Arclight Stage One suspension package was fitted, which includes power front disc brakes. This upgrade significantly improved the driving experience, offering a safer and more controlled ride compared to the original setup.

Engine and Transmission

The original engine was long gone, replaced with a 340 horsepower Ford 302. This powerhouse is equipped with a high-performance carburetor and intake manifold, along with a hydraulic roller camshaft. The engine breathes through advanced cylinder heads and an ignition system that ensures optimal performance. Exhaust gases are expelled through stainless headers into a 2.5″ exhaust system, providing both efficiency and a throaty growl.

Managing this power is a Tremec T-5 five-speed manual transmission, which takes the grunt and moves it out to a fortified rear axle fitted with a locker unit and 3.70 rear gears. This combination gives the driver a satisfying surge of power when the throttle is applied, ensuring a thrilling driving experience.

Interior and Comfort

Inside, the fully sound-insulated and carpeted cab offers a quiet and comfortable ride. Modern air conditioning has been seamlessly integrated into the original Ford “Polar-Aire” A/C unit, providing a touch of luxury. The wiring has been completely updated, eliminating any concerns about old, potentially hazardous electrical systems.

Wheels and Tires

The truck rides on chromed steel wheels wrapped in BFGoodrich Silvertown whitewall tires, sized 215/65R15 in the front and 255/70R15 in the rear. These tires not only enhance the classic aesthetic but also ensure reliable traction and handling.

The combination of these modifications and upgrades has transformed the 1961 Ford F-100 into a well-rounded, high-performance vehicle. All they need to do is fire off that 302, shift into gear, and get moving. The results speak for themselves.
