Featured Build: Gas Monkey Garage – The “Texas Skidmark” GMC C10

Gas Monkey Garage, known for their “bada** cars” took a 1967 GMC C10 from a small town in Fort Worth and torn it down to its bare bones with the intention of bringing it back as a stock-looking truck with a new look.  

This build, named “Texas Skidmark” broke the enthusiast internet when it was unveiled at SEMA 2023 and now we get a close look at how this icon was built with purpose.  

The Build 

To kick off this build, the Gas Monkey team started with a new chassis to allow for more tire clearance while sitting much closer to the ground. Paired with a new suspension setup, the team can raise and lower it whenever they need.  

Like many of Gas Monkey’s builds, power was a priority for the team. For this build, Richard Rawlings and the Gas Monkey Garage team opted for a 600HP Chevrolet L8T engine to ensure there was no sacrifice in drivability. Leading the team to opt for a more aggressive camshaft and intake to get to 600 HP. To complete the motor, they installed a pair of billet valve covers, and then after some tuning, it made around 575HP!  

Moving the engine and transmission into the vehicle properly was the next step and the limited clearance in the engine bay became a bit of a problem for the team. With some workaround and deliberation, they opted for cutting into the floor to make a new tunnel for the transmission.  

This truck’s powertrain is complemented by ultimate headers and a custom MagnaFlow 3″ stainless exhaust with MagnaFlow mufflers, 9-inch Currie rear end, Airlift 3P air ride system, Ride-Tech shocks, Wilwood Brakes and a set of one off 24″ wheels by JTX Forged. 

Gas Monkey has built over 200 cars in the last 20 years and the Texas Skidmark may be one of the best ever! Now, Gas Monkey Garage wants to give you the chance to drive this C10 home. You can enter to win at gasmonkeygarage.com.
