Financial Mistake

A 700HP, CUMMINS-POWERED OBS FORD

- Mike Mcglothlin

It’s true that you don’t have to spend big money to build the truck of your dreams. Even though Tyler Turay lightheartedly refers to the project shown here as a financial mistake, his ’95 Ford F-250 is actually living proof of that statement. A self-taught fabricator and no stranger to using a wrench, his changing tastes have influenced the look of his OBS Ford tremendously over the last 10 years—and doing nearly all the work himself has saved him a boatload of money. First, a Dana 60 replaced the factory Dana 50 TTB, six inches of lift was added, and the truck rode on 38-inch Mud Grapplers. Then came the ’05 axle swap, a leveled front-end, and 35s. Most recently, the old-school ¾-ton was lowered and graced with Toyo Proxes. Of course, the biggest change took place when Tyler ditched the 7.3L Power Stroke in favor of a P-pumped Cummins back in 2013.

7.3L Out, 5.9L Cummins In

After encountering multiple electrical gremlins with his modified-yet-aged 7.3L Power Stroke, Tyler came across a ’92 first-gen take-out engine listed on Craigslist. Because he had a strong desire to simplify the truck and make more horsepower—and the Cummins could be had for just $1,500—his mind was made up. However, knowing the first-gen Cummins’ VE injection pump would never provide the kind of fueling he was after, he sourced a P7100, front cover, injection lines, and everything else he’d need from a Ford F800 and went to work. The 265,000-mile, P-pump-equipped 5.9L was swapped in and life was good, for a few years anyway…
