A 650hp 6.0L Power Stroke Engine Makes this Dropped 1964 Ford F-100 Extra Cool

We always enjoy seeing truly different diesel-powered trucks, cars, and such. Dorian Reyna’s wild ’64 Ford F-100 is a rig that definitely falls in that category.
We’ve seen lowered trucks and cool engine swaps before, but Dorian has taken his to a level much higher than normal for modified classics. His F-100 has a full tube-chassis, custom front and rear suspension, and a 6.0L Ford Power Stroke engine on nitrous oxide, so we were eager to find out the story behind such a creative build.
“The truck sat for nearly two years in a San Diego neighborhood while I was stationed overseas,” Dorian says. “When I got back stateside to Houston, Texas, I learned the city had threatened to tow it away and crush it. So a buddy and I scraped up some dough and headed to California to pick it up.”

Upon arriving in Texas, the truck continued to sit with a blown-up 390ci gas engine while Dorian started his own business, Power Stroke Enginuities. “I met a lot of awesome people in the Marine Corps, and a few of them really wanted to see me turn the old F-100 into something special,” Dorian says. After constant pestering from his buddies Sgt. Eric Farias and Sgt. Jeremy Arsiaga, Dorian finally got to work.
A project that started as a “let’s stick a Power Stroke in a classic” build snowballed into a custom, tube-chassis rig. “At first, I was just going to build something with big tires in back, like a traditional hot rod, but I received so much help from friends and fabrication shops that I decided to go all out,” Dorian says.
In this case, “all out” means the F-100’s original frame was scrapped, and a full square-tube chassis was built by Chassis Fab, in Pasadena, Texas. The frame presented some interesting issues, as the front rails have to be wide enough to facilitate installing the diesel engine yet narrow enough to incorporate long-travel A-arms and 275-series tires. The rear of the truck was no less of a challenge, as Dorian still wanted the same big-tire look he had initially planned. That means a custom four-link, extremely narrowed rear axle, and an airbagged rear suspension.
There’s more to the low-slung look than just a custom frame and suspension, however. The F-100’s transmission tunnel and firewall also had to be altered in order to clear the Ford 5R110 five-speed automatic transmission and to allow space for the 6.0L engine. Vertical height transitions were also an issue. So, to alleviate those problems, the hood has a 3-inch cowl scoop, and the oil pan is shortened 2 inches for times when the truck is lowered to the ground.

Even with all the fabrication work finished, the project was still a long way from being considered “complete.” “I wanted it to make some impressive numbers on the dyno, so I couldn’t just stick a stock engine in it,” Dorian explains. So a completely rebuilt ’05 powerplant (featuring forged internals), 66mm turbocharger, upgraded fuel system, and nitrous were added. Jose Jimenez at Speedlab Creations was also a big help in the final stages, as he fabricated the truck’s intake and exhaust piping, intercooler, and radiator. Power Stroke Specialists in Miami, Florida, also helped in the late stages of wiring and getting the truck running.
“The first time I hit the key and fired it up, I knew all the hard work was worth it,” Dorian says. “People love the truck, they love the tribute seats, they love that it’s a diesel, and they love that we stuck some 18-inch meats out back.” While Dorian’s Ford is difficult to place into one specific category, the result of his five-year effort is a truck that most won’t soon forget.

We can honestly say Dorian Reyna’s ’64 Ford F-100 is the lowest-sitting diesel we’ve ever seen. Although its ride height can vary by as much as 11 inches, with the airbags empty, the frame, bumpers, and even oil pan are virtually on the ground.

The front suspension is a mix of McGaughys Suspension Parts drop spindles, custom A-arms, and Air Lift airbags fitted in a custom-notched frame. The ultra-long A-arms are necessary for the F-100 to have the correct suspension angle while driving yet tuck the mammoth 275-series tires when fully lowered.

The Chassis Fab frame extends all the way to the rear of the truck, where a custom four-link suspension is incorporated. The four-link uses remote-reservoir Fox Racing shocks as its main damping source.

In addition to the shocks, Air Lift Performance airbags are mounted behind the narrowed GM 14-bolt rear axle to help assist in raising and lowering the truck. The big bags are connected via twin Viair compressors and tanks for quick adjustments.

Other than the custom 3-inch steel cowl hood, the rest of the truck is farm fresh. The chrome bumpers are new, but everything remains in various states of weathered paint, primer, and bare metal.

Dorian envisioned big dyno numbers for the 6.0L-powered truck, so the donor engine was rebuilt with Carrillo rods, River City Diesel pistons, and ARP rod bolts and head studs. Without nitrous oxide, the engine puts out an estimated 650 rear-wheel horsepower and 1,100 lb-ft of torque.

A couple of bends from Speedlab Creations and an AFE air filter later, and Dorian’s truck has an air intake system. The filter is closer to the radiator to make room for the big front tires when the truck is dropped.

The factory variable-geometry turbo was ditched for a 66mm BorgWarner S300, mounted with a Cutting Edge Diesel swap kit. The compressor pushes 45 psi of boost into the engine and is responsible for the Power Stroke’s 650 hp (without nitrous).

In front, virtually everything had to be fabricated for the F-100. The radiator, intercooler, and all of the air intake piping was built by Jose Jimenez at Speedlab Creations.

If 650 hp isn’t enough, a Nitrous Express Diesel Stacker nitrous-oxide kit is available to add another 200-plus horsepower at the touch of a button.

Since there’s no room to hang a filter assembly below the truck, an Aeromotive A1000 lift pump and CAT filters from Marty’s Diesel Performance hang from the cab, giving the outside of the truck a little color.

Dorian wanted both the inside and outside of the truck to look like an original barn find, so the ’64 F-100’s interior is relatively unmolested.

One concession to modern technology is an SCT Livewire monitor, which allows the driver to keep tabs on such engine essentials as boost, coolant temperature, and exhaust gas temperature.
Photo 17/19   |   015 DSLP 160800 FORD Slammed Six Liter F100 Seat
Dorian gets a lot of questions about the seats in the truck. As a former U.S. Marine, he wanted to pay tribute to his friends, and he commissioned these custom seats to be designed and built by Ryan Alford at Sheetmetal Designs.

A set of 275/40R20 Nitto Invo tires fills the front fenderwells. They’re mounted on 20x9 American Force Independence SS8 wheels.

It’s hard to tell from the side, but Dorian’s F-100 actually has Pro Street rubber tucked into the bed. At 18 inches wide, the Mickey Thompson Sportsman S/R tires give the truck a very unique look.
