Corvette LS3 Swapped GMC Sonoma Truck Built for Street & Drag

If you were to take a stroll down the memory lane of America’s car culture, you would likely stumble upon the compact pickup trucks that reigned supreme in the late ’90s and early 2000s.
The GMC Sonoma, along with its Chevy S10 sibling, played a significant role in the street scene of that era. Like a chameleon, the Sonoma was known for its versatility, able to blend into the background of a construction site, or catch the eye as a sleek custom street machine. Light and compact, it offered an ample playground for modifications and quickly won the hearts of gearheads.

For the fans of American muscle cars, a modded S10/Sonoma is more than just a statement; it’s a testament to an era where the mini truck scene was an icon of street performance.
It was here that the real magic happened: the gentle humdrum of the four and six-cylinder engines were replaced by the throaty rumble of powerful V8s. The Sonoma quickly transitioned from being just another truck, into an epitome of speed and power that muscle car fans had long associated with bigger, bulkier vehicles.
Such transformations were, and still are, met with sheer awe, admiration and, at times, bewilderment. How could a seemingly unassuming compact truck pack such an unexpected punch?
The answer lies in the genius of the modifications – specifically, engine swaps – that gearheads across the country have been carrying out for decades. And that brings us to our main event – a modded, mean, and incredibly fast 1998 GMC Sonoma.
About The Model
The GMC Sonoma, first introduced in 1982 as a sibling to the Chevrolet S10, came as a compact pickup that was both practical and affordable. Known for their reliability and versatility, these trucks became a go-to choice for many. Over the years, the Sonoma has undergone various revisions, with the second generation (1994-2004) being most notable for the fans of performance modifications.
It was in this era that the Sonoma began to carve out its place in the heart of the American muscle car culture. Its compatibility with larger, more powerful engines, and the abundance of space for customization made it a prime candidate for gearheads looking to create a muscle truck.
LS Engine Swaps
When it comes to engine swaps, few are as universally admired as the LS swap. Known for its compact design, reliable operation, and high-performance output, the LS series engines from General Motors are often the go-to choice for gearheads. Whether it’s for the street or the strip, an LS engine’s power-to-weight ratio and simplicity in terms of modifications make it a perfect match for a compact truck like the Sonoma.
The Build: 1998 GMC Sonoma with LS3 Corvette Motor
Owned and modified by Justin Hayward, this 1998 GMC Sonoma is not your run-of-the-mill truck. Powered by a 6.2L LS3 Corvette Motor, it boasts a Stage 4 Brian Tooley racing cam and Stainless Works long tube headers. The full custom 3” exhaust done by Brows Exhaust, along with an 8.8 rear end from a Ford Explorer, propels this Sonoma to clock a ¼ mile in 11.1 seconds at 121mph – an impressive feat considering the 95-degree weather.

The truck is suspended on fully adjustable QA1 suspension, bolstered by Cal Tracs Traction Bars. The street setup consists of 18×4.5 Front Weld s71 RTS wheels and 15×10 on the rear with 275/60/15 Mickey Thompson ET Streets. However, when it’s time to hit the drag strip, the Sonoma switches to 15×4 wheels with Moroso DS2 tires and 15×10 rears with Hoosier 28x10x15 slicks.
But this Sonoma is not just about power and performance. It’s about style as well. It sports a custom blue color, Checkmate stepside flush mount tonneau cover, a step shaver roll pan by Street Scene, a shaved tailgate, and Street Scene mirrors. The GMC Envoy front bumper and 2” cowl hood with trackspec hood vents complete the look of this speed demon.
