The 1966 Chevrolet C10 pickup truck, an emblem of classic American utility and style, has been transformed into a true “Big-Block Beast” by its dedicated owner, Endicott, from Westerville, Ohio. While the C10 series itself, part of Chevrolet’s C/K line of trucks, began its journey in 1960 and evolved through several generations, the 1966 model represents the culmination of the first generation’s refined design. Known for its robust frame and straightforward engineering, the C10 was a versatile vehicle used for everything from farm work to daily commutes. However, this particular 1966 C10 transcends its humble origins, having been meticulously customized and equipped with a monstrous engine, elevating it from a reliable workhorse to a radical showstopper and drag strip contender, embodying the spirit of pure American horsepower.
A Radical Transformation: Endicott’s 1966 C10 is a testament to extreme customization and personal passion. While the truck utilizes a GMC frame and cab, it proudly wears a 1966 C10 front end, creating the familiar and beloved Chevrolet C10 profile. When Endicott acquired the truck nearly four years ago, it was a project in progress, with many components delivered “in baskets” from a previous owner who had already tubbed the vehicle. Originally painted a “ruddy brown,” the truck now sports a menacing tan primer finish, giving it a raw, drag-racing aesthetic that Endicott currently enjoys. He may eventually paint it the shade of blue already present on the bed-less rear section, but for now, the primer look perfectly suits its aggressive character.
Exterior Details and Materials: The body of this formidable C10 is crafted from traditional steel, maintaining its authentic vintage feel. However, to enhance its performance-oriented nature, the hood and its aggressive hood scoop are made from lightweight fiberglass. Interestingly, this year’s Goodguys Summit Nationals in Columbus, Ohio, marked the first time Endicott even used a hood on the truck, as he previously preferred to run it “open air,” allowing the massive engine to be fully exposed in true hot-rod fashion. The commitment to performance extends to the fuel system, with the ZZ572/720R engine fed by dual 12-gallon fuel cells, each supplying 110-octane racing fuel, ensuring it has the necessary high-octane diet. Exhaust gases are aggressively expelled through a Flowmaster system featuring side exits, delivering an unmistakable, powerful roar.
Interior Evolution: The interior of this 1966 C10 is a clear reflection of its performance focus. It is mostly stripped down, highlighting its purpose as a high-horsepower machine built for racing and show. While still a work in progress, it features all the necessary gauges to monitor the mighty engine’s vitals. The cabin is equipped with bucket seats, offering the driver and passenger a secure position during intense acceleration. A roll-bar setup was already installed when Endicott purchased the C10, providing an essential safety feature for a vehicle of this caliber. The minimalist approach to the interior underscores the truck’s dedication to raw power and speed.
Powerhouse Engine and Performance: The heart of this 1966 Chevrolet C10 is nothing short of radical: a Chevrolet Performance ZZ572/720R crate engine. This colossal 572 cubic inch (9.4L) Big-Block V8 is factory-rated at an astonishing 727 horsepower and a massive 680 lb.-ft. of torque, making it a true beast on the pavement. The engine features a robust cast-iron block with four-bolt main caps and an ultra-strong, all-forged rotating assembly, built to withstand extreme forces. A mechanical roller camshaft works in conjunction with high-flow, aluminum rectangular-port cylinder heads to maximize power output. Topping this formidable mill is a Dominator-style 1150-cfm carburetor, ensuring precise fuel delivery. This engine is undeniably built for racing, designed to dominate drag strips, but it also captivates onlookers at car shows and cruise-ins with its sheer presence and incredible sound.
Drivetrain and Chassis Management: To manage the immense power of the 572 cu.-in. Big-Block, the engine is mated to an FTI Performance TH400 transmission, specifically engineered to handle up to 700 horsepower. This robust transmission sends power to a durable 12-bolt rear end, featuring a 4:11 gear ratio, optimized for aggressive acceleration. Power is transferred via a custom aluminum driveshaft, ensuring strength and efficiency. The vehicle’s traction on the pavement is secured by formidable Mickey Thompson 18×5 rear tires, designed to hook up the massive horsepower. For stopping this high-horsepower vehicle, disc brakes are utilized at each corner, providing reliable and effective deceleration. Furthermore, wheelie bars are installed at the rear, a crucial safety feature that helps prevent the truck from tipping over during powerful launches. Endicott meticulously modified various brackets and bars for optimal fitment and adjusted the suspension setup to better handle the immense horsepower and weight of the engine, ensuring a cohesive and controlled performance machine.
The Builder’s Vision and Legacy: Endicott, a talented builder and welder, undertook nearly all the work on this impressive truck himself, a testament to his skill and dedication. He enlisted his sons for assistance with the engine and transmission installation, making it a family endeavor. The truck was already set up for a Big-Block Chevy engine and TH400 transmission, which minimized the fabrication work required in the engine bay for the 572 cu.-in. powerplant. Endicott, now retired from Pepsi-Cola, dedicates his time to perfecting his C10 and attending various shows and tracks. He credits online resources like YouTube for many of the tips and tricks he’s learned, showcasing a modern approach to classic car building. Coming from a “GM family” with a history of cool cars, Endicott’s 1966 C10 stands as his ultimate creation, proving that he can build something “way more wicked” than anything his family had before.
