Loyd Finds the Perfect ’72 C10

After searching for only a few months, Loyd’s hunt for the perfect pickup lead him to Dave Clark at Early Classic Enterprises (ECE), and a certain ’72 C10. Clark originally purchased the truck back in 1995 as a test mule for ECE’s vast collection of high-performance suspension components and continued to use the truck at the ECE headquarters. After only one look, Loyd knew this was the one; this was the truck he had always lusted for. Clark and his crew had built an amazing pickup, and Loyd knew that with a few personal touches, the truck would be perfect.

A Rigorous Frame-Off Restoration

Clark and his crew at ECE began the project working from the ground up. After dismantling the truck, the frame and suspension went through a rigorous restoration. Blasttech located in nearby Fresno, California, removed any rust and scale before powdercoating the chassis in a clean satin black finish. ECE repaired, rebuilt or replaced every suspension component using new Moog hardware before reinstalling it all onto the fresh framerails. Up front, ECE installed a set of 2-1/2-inch-dropped spindles, and 2-inch-dropped coils to help bring the truck closer to the ground. After removing the stock 12-bolt rearend and installing an Auburn limited slip and 3.42 gears, Clark implemented 6-inch dropped coils and an adjustable Panhard bar to complement the front drop and re-center the rearend.

Upgraded Driveability and Rolling Stock

To improve driveability and handling, a 1-1/4-inch sway bar resides beneath the truck, and a quick ratio steering box replaces the worn out original. Since the original shocks were long overdue for a change, ECE fitted the truck with a set of KYB gas shocks. One of the first things to change when Loyd purchased the truck were the wheels. Clark installed chrome five spokes several years earlier, which Lloyd felt were a bit dated. Rolling stock for the Cheyenne now consists of Boyd Coddington 18- and 20-inch Sultans wrapped in BFGoodrich rubber. Visible through the windows of the Coddington wheels are 12-inch front and 11-inch rear cross-drilled rotors.

The Prototype ZZ4 Crate Engine

Residing under the hood of the vintage Chevy is a GM Performance Parts ZZ4 crate engine. Now what makes this particular engine special is that it is ZZ4 production engine number 3. Originally built as a prototype for the GM Performance Parts program, the engine made its way out of GM and into this particular Cheyenne. Rather than try to modify GM engineering’s effort, Clark capitalized on the factory performance. The ZZ4 is topped with GM Performance Parts 58cc aluminum heads, aluminum intake and a Jones Performance Quadrajet. Wanting to keep the truck’s appearance stock, Clark fitted the ZZ4 with the factory accessories, including the original California smog pump and A/C compressor. To add a little brightwork beneath the hood, a chrome breather and aluminum Corvette valve covers rest atop this potent powerplant. With driveability high on the list, Clark chose to install a 4L60E trans to keep the ZZ4 rpm down and fuel mileage up.
