Exterior Excellence: The fiberglass body of this classic Corvette was expertly repainted in a vibrant red around 2016 by Cotati Speed Shop. During this process, the flared front fenders were returned to their original factory style, and the iconic split chrome bumpers were re-chromed to a brilliant shine. Adding to its distinct appearance are 1967-style side vents and taillights, a commanding big-block-style hood, and attention-grabbing side-outlet exhaust pipes equipped with heat shields. Notably, the Corvette script badges have been removed, and the seller points out the application of transparent paint-protection film in the areas behind the wheels, safeguarding the finish. For an in-depth visual tour and historical context, a detailed vehicle and history walkthrough is available in the video gallery.

Wheels, Suspension, and Brakes: This Corvette confidently rides on American Racing 15″ Torq Thrust wheels, featuring polished lips and contrasting gray centers. These stylish wheels are wrapped in Vredestein Sprint Classic tires, which were installed in 2021, ensuring a blend of classic aesthetics and modern grip. Enhancing the driving experience is the inclusion of power rack-and-pinion steering, providing responsive and effortless control. The suspension system has been upgraded with Bilstein shocks, working in concert with the rear transverse leaf spring to deliver a balanced and refined ride. Bringing this powerful machine to a halt are Wilwood disc brakes, featuring impressive six-piston front and four-piston rear calipers gripping slotted and drilled rotors, offering substantial stopping power and enhanced brake cooling.

Interior Refinements: The interior of this 1966 Corvette has been thoughtfully refurbished, creating a comfortable and stylish cabin. The headliner and carpets have been replaced, and the seat frames have been powder-coated for durability and a clean look. A 1967-style dashboard and emergency brake assembly have been installed, along with replacement seat foam and luxurious Al Knoch red leather covers, providing both comfort and a touch of classic elegance. For added safety, Simpson multi-point harnesses are fitted to a removable brace. Modern conveniences include Vintage Air climate control, ensuring a comfortable environment regardless of the weather, and a Custom Autosound receiver for enjoyable audio entertainment. A fire extinguisher is also readily accessible.

Instrumentation and Controls: The wood-rimmed steering wheel, mounted on a convenient tilting column, frames the rebuilt factory-style instrumentation. The five-digit odometer currently displays 68k miles, with approximately 17k miles added during the current ownership. However, the seller indicates that the mileage is not accurate, and the total mileage of the vehicle is unknown.

Power and Performance: Under the big-block-style hood resides a formidable GM Performance ZZ427 V8 engine, installed in 2015. This potent engine was meticulously assembled with a forged rotating assembly, a hydraulic roller camshaft, and high-performance aluminum oval-port cylinder heads, further enhanced by MSD ignition for reliable spark. The engine breathes deeply through a Holley 800-cfm carburetor situated atop an aluminum dual-plane intake manifold, ensuring optimal fuel delivery and airflow. Exhaust gases are efficiently expelled through Hedman headers and the distinctive side pipes, contributing to both performance and a classic muscle car sound. Cooling duties are handled by a high-capacity Griffin aluminum radiator paired with an electric fan, maintaining optimal engine temperature. The battery was recently replaced in 2024.

Transmission and Drivetrain: Transferring the ZZ427’s power to the rear wheels is a robust Tremec TKO 600 five-speed manual transmission, equipped with a high-performance McLeod dual-disc clutch kit for smooth and reliable engagement. To accommodate this upgraded transmission, a fabricated cross-member was installed, and the driveshaft, U-joints, and slip yoke were replaced, along with the transmission mount, ensuring a strong and reliable drivetrain. The seller also notes that the frame underwent stitch-welding during the refurbishment process, enhancing its structural rigidity.

Trim Tag Decoding: Decoding the trim tag reveals valuable information about this Corvette’s original specifications: J17 indicates a June 17th production date; Style 66 437 denotes a 1966 Corvette coupe; Body S4437 is the St. Louis body number; Trim STD signifies black vinyl upholstery; and Paint 974 indicates the original Rally Red exterior color. It’s worth noting that the current California title is a duplicate.
