Father-Son Turn Chevy Truck Into 1,000‑HP Beast
- Street Muscle spotlighted a San Jose father-son build on May 4 — Randy T. and his 16-year-old son Corbin turned a 1970 Chevy C10 into a 1,000-hp street truck. - The truck keeps its stock frame but adds a supercharged 6.2-liter Wegner LS3, T56 Magnum six-speed, and gearing Randy says supports 170-mph runs. - It matters because the build is mostly home-fabricated — a DIY C10, not a shop checkbook special.
Classic truck stories usually split two ways. Either the build is a clean restoration, or it’s a blank-check restomod done by a shop with a parts catalog and a lift bank. This one lands somewhere more interesting. A father in San Jose and his 16-year-old son took a 1970 Chevy C10 apart, rebuilt it from the chassis up, and ended up with a Whipple-blown, 1,000-plus-horsepower truck that can do grocery duty and track duty in the same week. (streetmusclemag.com) ### Who built this thing? The truck belongs to Randy T. — identified elsewhere as Randall Thurston — and the build became a shared project with his son Corbin. Street Muscle says the pair started with a clean stock short-bed C10 found in Fremont, California, then turned it into Randy’s biggest build yet(streetmusclemag.com)d a project that doubled as bonding time. (streetmusclemag.com) ### What changed from stock? Basically, almost everything that matters. Randy says they tore the truck down completely and rebuilt it from the chassis up, with about 95% of the fabrication, metal work, body work, roll cage, and exhaust done by him rather than outsourced. The catch is that the truck stil(streetmusclemag.com), which gives the whole build a more stubborn, do-it-the-hard-way feel. (streetmusclemag.com) ### What’s making 1,000 horsepower? Under the hood is a 6.2-liter Wegner LS3 with a Gen 5 3.0-liter Whipple twin-screw supercharger. Fuel comes from a Boyd 20-gallon cell through an Aeromotive system with PTFE lines and a 5.0 brushless pump, and engine management runs through a Holley Dominator ECU with(streetmusclemag.com)on, with torque in roughly the same neighborhood. (streetmusclemag.com) ### How does the truck survive that? Horsepower is the easy brag. Keeping the truck together is the harder trick. The LS3 feeds an American Powertrain Stage 3 T56 Magnum six-speed rated for 1,100 lb-ft, plus a Centerforce twin-disc clutch, a QuickTime bellhousing, a QA1 carbon-fiber driveshaft, and a Qu(streetmusclemag.com)e real goal wasn’t dyno-sheet theater — it was repeatable abuse. (streetmusclemag.com) ### Is it just a straight-line truck? No — and that’s what makes it more interesting than the average giant-engine swap. QA1 says the truck runs complete front and rear suspension kits with MOD shocks and sway bars. Randy also says first through fourth are meant for autocross or track use, while fifth a(streetmusclemag.com)highway missile, and old-school pickup silhouette. (streetmusclemag.com) ### What’s the wildest claim here? The speed claim. Randy says the gearing supports “high-speed runs — like Bonneville — up to 200 mph,” and that the truck has been reliable enough to “go to the grocery store or go 170 mph.” That doesn’t mean it has officially done 200, but it does tell you how he engineered the package — not as a burnout toy, but as something with real top-end intent. (streetmusclemag.com) ### Why does this resonate so much? Because C10 culture loves the idea that an old Chevy truck can be anything — cruiser, drag truck, autocross build, showpiece, family project. But turns out this one hits a deeper nerve. It’s not just fast. It’s hand-built, mostly at home, and tied to a father teaching his son how to make something difficult and real. In a car scene full of outsourced perfection, that still stands out. (streetmusclemag.com) ### Bottom line? This isn’t just a 1,000-hp Chevy truck. It’s a reminder that the coolest builds still come from garages — especially when the story includes the kid holding the flashlight and eventually picking up the wrench too. (streetmusclemag.com)
