The 1966 Chevrolet C10 known as “Tiffany” represents a unique creative journey within the walls of Classic Car Studio. This project started as a conceptual melting pot during shop breaks and after-hours brainstorming sessions. Unlike standard restorations, Tiffany embraces a rugged patina look that hides a world-class level of modern engineering underneath. The truck serves as a rolling showcase for high-end metal fabrication and advanced fuel injection technology. Every component was selected to bridge the gap between vintage character and extreme horsepower. It features a complete chassis overhaul and a bespoke interior that rivals modern luxury vehicles. This build is not just a shop truck; it is a manifestation of pure automotive passion. Currently, the truck stands as one of the most recognizable custom C10 builds in the heritage community. It proves that a 1966 Chevrolet C10 can be both a workhorse and a high-performance masterpiece. This truck truly speaks for itself once you look past the weathered exterior.
Mirror Image Turbos and LS1 Engineering
The mechanical heart of this 1966 Chevrolet C10 is a built 346 LS1 engine equipped with high-flowing LS6 heads. What truly defines this powerplant is the pair of Nelson Racing 64mm mirror-image turbos. These units sit prominently in a clean engine bay, connected by custom stainless turbo piping. A Holley Dominator EFI system manages the complex fuel and air requirements of the twin-turbo setup. To feed the beast, the team installed 120 LB/HR injectors and a VR2 brushless fuel pump. A Sniper intake manifold and a massive 105mm throttle body ensure the engine breathes without restriction. This combination delivers a level of performance that far exceeds anything originally intended for a 1960s pickup. Every wire is tucked away neatly using an American Autowire harness for a professional, race-grade finish. The cooling system and fuel rails are all top-tier billet components designed for maximum durability. Consequently, the truck offers a visceral driving experience backed by precise digital control.
AccuAir Management and Fabricated Chassis Work
Stance is everything for a custom 1966 Chevrolet C10, and Tiffany sits perfectly thanks to an AccuAir E-Level system. This air management setup allows for on-the-fly height adjustments, giving the truck a slammed look when parked. The foundation consists of a custom-built front half-frame paired with a Porterbuilt rear chassis. RideTech shocks are used at all four corners to provide a controlled and comfortable ride despite the low height. Power is sent through a TCI Turbo 400 transmission to a stout Ford 9-inch rear end. A TruTrac limited-slip differential with 3.73 gears ensures that both rear tires fight for traction. The truck rolls on GM transport wheels wrapped in performance-oriented Pirelli tires for a classic industrial look. All the sheet metal in the body and bed has been custom fabricated to accommodate the new geometry. This extensive metalwork is a one-off effort that separates Tiffany from catalog-built trucks. It is a harmonious blend of heavy-duty hardware and sophisticated electronic control.
LS1 Twin-Turbo Specs and Performance Hardware
The 1966 Chevrolet C10 “Tiffany” generates immense power from its 5.7-liter twin-turbocharged LS1 V8 engine. With 64mm Nelson Racing turbos and Holley Dominator management, this truck is built for high-boost reliability. The exhaust is a custom stainless steel system that provides a distinct, aggressive note. Cooling is managed by a high-capacity radiator, while a VR series regulator maintains steady fuel pressure. Inside the cab, a 7-inch touchscreen display provides real-time data from the Dominator ECU. The driver can monitor everything from boost levels to oil pressure with a single glance. Every performance part, from the billet fuel filter to the 120-pound injectors, was chosen for high-output duty. This truck is capable of shredding tires at will while remaining a drivable, reliable street machine. It represents the pinnacle of the “patina sleeper” movement where performance is the ultimate priority. The mechanical specifications are a testament to the skill of the Classic Car Studio team.
