Jimmy Stewart’s Slammed Diesel-Powered War Rig

When Jimmy Stewart decided to build his dream truck, he didn’t just aim to turn heads—he aimed to break necks. His 1965 Chevrolet C10 isn’t just slammed to the ground and bagged; it’s stuffed with diesel muscle, packed with custom work from front to back, and it goes by the name WARPNY1. And yeah, it definitely lives up to the name.

This C10 is a full-on, no-BS shop truck gone mad. Straight outta Edmond, Oklahoma, Jimmy built something that doesn’t just sit pretty; it throws hands with anything on the street or the show floor. And if you’re wondering what makes this build different from the sea of patina-clad pickups out there, buckle up.

 The Heart of the Beast

Tucked under the hood is a 6.1L straight-six Cummins pulled from a ’94 Dodge. But this ain’t your granddad’s farm truck engine. This beast is stroked with a 6.7 crank, decked out with Mahle pistons, fire-ringed heads, billet rocker supports, and ported everything. It’s topped with two compound turbos, a PhatShaft 62/65/12 feeding a massive 75/96/1.32. That’s not just for show either; it’s a “hold on and pray” kind of setup.

Jimmy didn’t slap this thing together. Mark Beatty from OKC handled the engine build, and it has serious guts: a Hamilton 188/220 cam, hand-cut rings, and a custom stainless exhaust that growls like an angry bear. Cooling is handled by a Derale setup mounted right in the bed because there wasn’t room up front. Why? Oh, just a little thing called a window in the hood cut to clear that massive snail hanging off the side.

 Power to the Pavement

All that torque hits an Allison 545 trans with a Gear Vendors overdrive split out back. And before you ask, yeah, it’s been cooled properly with a bed-mounted setup. Putting power to the wheels is a Quick Performance 9-inch billet rear end with 3.00 gears and a locker, which means this thing can roast tires or cruise at highway speeds with ease.

The whole chassis got the royal treatment. Underneath is a Porterbuilt front Dropmember and Stage 3 back half, all sitting on Air Lift 3H air management. The frame is boxed and reinforced with three extra crossmembers to keep it from twisting when all that torque hits. Phil Alexander from Raven’s Speed Shop in Marlow, Oklahoma handled the chassis work, and it shows.

The wheels? Jimmy opted for 22×10 Schott SL65s wrapped in Hankook Ventus 265/35R22s. And if you’re wondering if it rubs—only at full tilt with the bags dumped. But let’s be real, it looks way too good laid out to care.

 Show Stopper, Street Capable

Even with all that going on, the C10 is just as much about the show. Jimmy ditched the original firewall, shoved it back 8 inches, and hacked the front fenders to clear the steering setup. Floating rear fenders, one-off headlight blinker combos, and a custom trim paint mix finish the job.

The truck is coated in PPG DDC Black single-stage paint, with the trim in a custom PPG mix. Curtis Hutton from Hutton Paint and Body out in Marlow laid it all down like a pro. It’s deep, mean, and gives off a vibe that says, “Don’t touch!”

 Inside the Cockpit

Jimmy kept it classic inside, rocking a factory seat wrapped in black leather by Eli’s Easy Trim in OKC. A Momo Montecarlo steering wheel and Dakota Digital VHX gauges bring some modern flavor. Dash speakers were fabbed into the top of the dash to look factory, and even the throttle pedal started life as a Wilwood brake pedal. The whole bezel was smoothed and welded to hide switches, giving it a slick, clean look that doesn’t scream for attention—it earns it.

Power windows, custom wiring, air tanks, compressors, fuel tank, A/C condenser, and even the trans cooler were all relocated to the bed. Everything’s tucked, hidden, and clean.

 Built for the Long Haul

Jimmy’s advice for anyone diving into a build like this? “Gather parts for almost everything before you start. With enough time, money, and patience, you can build anything.” That’s the kind of grit and grind this truck stands for.

From Dino’s Git Down to C10s in the Park, WARPNY1 is putting Oklahoma builds on the map. It’s not just a truck; it’s a statement. Built, not bought. Loud, proud, and slammed to hell.
