HARD WORK PAYS OFF

A CUMMINSSWAPPED ’08 SUPER DUTY PACKING A 4R100 AND 700 HP

An ’08 Super Duty was a truck that John Schomberg always wanted. Unfortunately, the 6.4L Power Stroke under the hood of his King Ranch F-350 suffered a bottom-end failure within the first 6,000 miles of ownership…and with only 103,000 on the odometer. Following the local Ford dealership’s quote of $17,000 to replace the engine, naturally John began to weigh other options. After reaching out to Jeff McCord at LinCo Diesel Performance, the two parties had a game plan—and it involved converting the Ford to Cummins power. “LinCo wasn’t the cheapest, but they took the time to walk me through everything involved in the Cummins swap,” John told us. “And honestly, they were one of the only shops that wanted to do it.”

Unbeknownst to many, a Cummins conversion isn’t typically the most affordable path for Ford owners. Sure, the end result is a simpler engine with what the owner hopes will be a less problematic means of propulsion, but performing a Cummins swap is anything but easy—or budget-friendly. And sometimes, there isn’t even a guarantee the Cummins you install will last. Case in point, the original ’06 take-out engine John went with lost a factory piston cooling nozzle while drag racing, the result of which was a melted piston in cylinder number 4.
