2016 Ford F-350 King Ranch

Nobody’s Fuel

Every once in a while, we run into a build that serves as a stark reminder of how lucky we are to be living in this era of diesel performance, a truck that is not built to be the “ultimate” example of anything, but instead one that is put together with goals in mind and brains in use. The stomper we are talking about is Jeff Teasley’s ’16 Ford F-350 King Ranch, which was built because Jeff wanted to have a killer rig capable of doing work his other trucks cannot. This is not an F-350 that is drastically altered mechanically, aesthetically, or otherwise. This is a pickup that has had its looks, stance, and performance enhanced to live up to Jeff’s vision of what a work-and-play rig can be.
It is impossible to deny that today’s stock diesel platforms are fantastic foundations with which to build performance. In this case, we are talking about the 6.7L Power Stroke engine that motivates Jeff’s F-350. In fact, the internals of this engine have never seen daylight. “I wanted to do a daily driver,” Jeff says. “The goal was a clean build that could be worked. After talking about it, we kept the fuel stock and just focused on airflow. With the new 6.7L-powered trucks, you can make lots of power with stock fueling.” Jeff is not kidding. The Power Stroke makes 670 hp and 1,350 lb-ft of torque with the original fuel system—no high-volume lift pump or larger injectors, only the factory-installed bits and pieces.

Mike Haller at Haller’s Repair took the lead on the build, and his recipe for making reliable, hardworking power centers around airflow in both directions. We’re talking about getting the air in and exhaust out. For the pressure side of the program, Mike settled on a Midwest Diesel–prepared BorgWarner S475 turbocharger kit. This setup keeps the stock turbo in place and, with the addition of the S475, transforms the already tough 6.7L powerplant into a draft horse that can gallop. The proof is in the boosted pudding. “I see 58 psi at peak,” Jeff says. “I can be towing up a big grade with 16,000 pounds behind me and the EGT doesn’t crack 1,200 degrees.” The underhood plumbing is artwork. No Limit Fabrication’s polished pipes take the job of moving air into the engine and turn it into functional sculpture. What does Jeff’s rig pull that weighs so much? The big F-350 basically rolls with either a 40-foot fifth-wheel trailer or 25-foot equipment hauler behind it. This big boy is earning a living for sure.

With the truck’s elevated stance and the heavy workloads it’s subjected to, proper suspension is not just important for looks, it is also critical for safely handling the loads. An Icon Vehicle Dynamics leveling system carries that beef on stock axles with 3.55 gears. It is the foundation that keeps Jeff’s pickup heading down the road happily, along with Bilstein 5100 shocks, Hellwig Products sway bars, and One Up Offroad traction bars. In a working application like this (which is not designed to only be a dragstrip hero), making the right decisions for the components under the truck is vital. Wheels and tires are also an important part of the mix, and the 22x12 BMF Novakane hoops along with the 35x12.5R22 Toyo Open Country A/T II tires have proven themselves capable of handling the loads and the miles.

The exterior modifications of the ’16 F-350 follow the same pattern as the engine changes. Ford’s King Ranch styling isn’t changed; it’s merely enhanced by a Rigid Industries lightbar and a Retrax bedcover, plus Recon taillights, third brake light, and mirror lights. Again, the idea here was to build a good-looking and hard-running daily driver. Every one of the exterior tweaks helps the truck work a little better than it did when it left the factory.
Photo 6/20   |   We always love the final designs of a particular styling generation, and the ’16 F-350 King Ranch has great lines right out of the box. Of course, the lift gives the rig more presence on the road, and the black wheels contrast perfectly with the white paint.
When we look inside the cab of the big white beast, we see Jeff decided to leave the F-350’s full-on living-room-style King Ranch treatments alone. Many truck enthusiasts believe there isn’t another interior available today that matches the Ford crew cab for luxury and comfort. Jeff obviously agrees. He did add an Edge Products Insight programmer to keep tabs on the engine and make on-the-fly tuning changes. The unit looks right at home in this big white Ford.
Photo 7/20   |   Other than the addition of an Edge Products Insight programmer, Jeff did not mess with the truck’s awesome stock interior. The King Ranch trim level is one of the most comfortable and inviting that any major manufacturer offers. While the truck puts in the work, Jeff rides in style!
During a build, it takes serious commitment to not fall into the classic case of project creep. In running this project, Mike definitely took Jeff’s rig in a direction where it is clear he did not fall victim to that syndrome. There are so many options and so much “easy power” to be made these days.
Project trucks like Jeff’s are great examples of how taking advantage of advancements in factory engineering can result in rigs that are built on a workingman’s budget. Many diesel enthusiasts get a little queasy at the idea of pulling apart an engine that is barely broken in, and this is a shining example of the fact that you no longer have to do that. The camshaft, cylinder heads, crankshaft, pistons, rods, and fuel system bolted into this F-350 are exactly as they were when the engine was originally assembled. Maximizing the 6.7L Power Stroke’s air intake and exhaust has definitely delivered Jeff the truck he wants and needs.
Photo 8/20   |   The back end of Jeff Teasley’s Ford works the hardest. This rig is often tasked with hauling heavy loads over long distances. That’s more proof that the Icon Vehicle Dynamics suspension is as functional as it is good looking.
Photo 9/20   |   We think this King Ranch F-350 is cool because Jeff showed a lot of restraint and still ended up with power and a very capable truck. There are no over-the-top graphics, wraps, or paintwork—just the solid appearance Ford designers penned.
Photo 10/20   |   Getting the wheel and tire package right can make the difference between a rig looking perfect and one that makes you look away. The black 22x12 BMF Novakane wheels are cool, and the 35x12.5xR22 Toyo AT2 tires are aggressive enough to get attention and strong enough to do work.
Photo 11/20   |   Rather than get crazy with a massive exhaust system, Jeff continued the theme of “classy and cool” with the pipe setup for his rig. While needing to improve exhaust flow, he did not want to detract from the truck’s appearance. So he went with a 4-inch MBRP package using an Aero muffler. You can hear him coming, but it is the kind of sound you want to hear if you love diesel performance.
