Trevor Lima’s Immaculate Resto-Mod C10
This Cummins powered Chevy C10 bodied Ford F250 chassis lifted 4×4 creation took Trevor Lima, of Diesel Performance Specialties, over three-years to build. He finished it just in time for SEMA 2018. It set him back a $150,000 to realize this dream build.

Lima has been in the industry for over six-years and created some impressive builds over that time. The last big one, before this Cummins C10 build, was a crazy six-door 2016 Excursion.

The Spark

Lima built an orange 1967 Chevy C10 2WD single cab short bed alongside his Dad as a young adult in their home garage. The build was nearing completion, with body paint, powder coated frame, engine and trans already done, when his parents got a divorce, and the truck was sold. That truck turned into the famous “Tootsie,” as it’s known in C10 circles.

The 2010 Ford F250 Frame benefited from a box and full reinforcement while an 8-inch suspension system from Fabtech helps soak up the bumps.

Between the build with his Dad and restoring a 1970 GMC 2WD in dark metallic green and white with woodgrain trim for his great uncle Pete Lima was hooked. He always wanted to make one for himself, but has always been a 4WD diesel lifted truck guy, so this creation is the culmination of those early build experiences and dreams.

Getting Started

Lima decided in 2015 that it was finally time to tackle a build like this for himself, in his personal style. The idea for this build started off as a cool halfway clean daily driver, but nothing over the top. Lima wanted a lifted 4WD, and wanted a Cummins diesel stuffed under the hood. He also loved the retro classic paint look, and couldn’t resist that orange two-tone.

As Lima started on the build he ran into problem after problem trying to get the big Cummins to fit in the original 1967 Chevy frame. In the end it wasn’t wide enough or strong enough to support the big diesel. A frame swap was going to be required.

Lima says that the running gear under the Dodge frame from the same vintage as the engine he chose, 2003-2007, was “the world’s worst,” so he decided to use a Ford chassis. He found the axles, steering, suspension, etc… to be superior to a 2000’s Dodge truck.


As he started working on the truck more and more he quickly realized that he couldn’t justify not doing the build perfect. He had built a nice 1995 K3500 Silverado several years before, with a 12 Valve Cummins in it, but when he was done he knew there were a few things he should’ve done differently.  Lima couldn’t stomach having that feeling again with this build.

Doing It Right

At this point the personal build budget went out the window and Lima focused on doing every aspect of this project just right, and to his personal style. He aimed to build a show truck that was an extremely capable weekend driver and was every bit as aggressive on the road as it would look.


Of course, as with most projects like this, it took much longer and cost much more than expected to build. Lima had to keep putting this personal build on the back burner as his business grew, he moved into a larger building, sold his house and the usual life events happened.

The Build

The 1969 Chevy K20 single cab body has been refurbished to better than OEM quality and updated with a billet grille. The classic Chevy body sits atop a 2010 Ford F250 chassis, which has been boxed and reinforced. A 2005 5.9L common rail Cummins has then been stuffed under the Chevy hood and between the Ford frame rails. The American truck trifecta has been achieved with this truck!


The Cummins has been bored .020 over stock, the block deburred and all new high quality internals fitted. Parts like Carillo Rods, Mahle Pistons, Hamilton cams, valves, lifters and pushrods and even a big S369 SXE Turbo with race cover and a billet wheel have been fitted. An Airdog 220 GPH, 12mm Stroker-BD Diesel Injection Pump and Exergy Injectors all add to this impressive engine package. An HP Tuner tuned by Firepunk Diesel helps the truck put down 1500 ft/lb torque and 800 HP.

Under the hood lies a fully built 5.9L Cummins with enough go fast parts to easily crest the 800hp mark without breaking a sweat.

Under the truck you’ll find Fabtech 8” lift springs up front and stock F250 leafs in the back, with a shackle flip. Pro Comp MX2 shocks keep the ride smooth over the rough Texas roads. The truck rolled on huge 24×14 Forged American Truxx 1909 Aries Wheels wrapped in 40×15.50 Toyo Mud-Terrains for SEMA, but normally rolls on classic 17-inch pacer wheels wrapped in 40×13.50 Toyo MTs.


A full custom interior is both modern and classic at the same time. It features seats out of a 2005 Chevy truck, OEM Dodge gauges and a full custom tan leather interior by Pacos Upholstery.

The list of upgrades on this truck is more than extensive, as Lima needed  to find ways to integrate the big Cummins into the Chevy body and Ford chassis seamlessly. A Firepunk Comp Stage 2 transmission turns custom B&W Driveline driveshafts while a ATS 3-piece stainless exhaust with MBRP flow through muffler let the Cummins breath easy. Touches like a custom 35 gallon aluminum fuel tank, dual optima batteries mounted on the frame rails and Amp Research powered side steps help keep this build tidy and functional.


Life With His Dream Truck

All in, Lima is super happy with how this build turned out and says he “doesn’t really have any plans in the future to upgrade it.” He built it the exact way he wanted, and correct the first time. He says “it has tons of power and drives like a dream.  It doesn’t need anymore work in my opinion. It turns more heads than you can count when its cruising down the road or driving by on a trailer.”

Build Sparks New Business

After this build started coming to life, it started gathering a ton of attention locally in California. People were stopping by Lima’s general auto repair shop to check it out. The more people came around he realized that there was an untapped niche in the diesel community where he was living. His general auto repair shop wasn’t doing great, as there were about 20 other repair shops on the same road and the competition was fierce.

The interior of Lima’s C10 is just as (if not more) impressive as the rest of the truck.

A lack of a quality diesel shop around was very evident, so he changed his shop’s name and refocused on the diesel market. Diesel Performance Specialties was born, and business was booming immediately. After only six-months he moved the business from a tiny 2,000 Sq ft shop into a huge 8,000 Sq ft space right off a major freeway.  Within several months at the new location, he even took over the 8,000 sq/ft building next door. Lima had found his niche and business is good.

Life Of A Show Truck

This build was winning local truck shows before the interior was even finished, even landing in a few local auto parts calendars. Lima never saw his creation as a SEMA truck, as he “figured it was too old and classic for the modern touches of the show.”


Truck Guru’s Cris Payne was looking for some SEMA trucks for the 2018 show and multiple people tagged Lima’s build on Facebook to be considered. In the end this custom diesel C10 build was upgraded with 24×14 American Truxx wheels and showcased in the company’s SEMA Show booth in 2018.



These days it’s been attending a few local shows and sitting in the shop not getting much drive time. It can currently be seen at the brand new Diesel Performance Specialties shop in Weatherford, TX.
