For Sale: 1966 Chevrolet Chevelle in Mesa, Arizona

Classic Car Addict is proud to offer this exceptional 1966 Chevrolet Chevelle SS for sale in our Mesa, Arizona showroom. This documented 138-code Super Sport underwent an extensive frame-off restoration that began in the early 1990s and was meticulously completed by a dedicated enthusiast over the course of more than a decade. Built with attention to detail and performance in mind, this Chevelle features the upgrades and enhancements that collectors and drivers alike are looking for.

The interior has been completely refreshed with TMI Sport R bucket seats front and rear, complemented by a new headliner, new carpet, stock-style door panels, and new door and window hardware throughout. An Ididit tilt steering column replaces the factory unit, while a Dakota Digital VHX gauge cluster provides gauges for fuel, temp, 160-mph speedometer, 8K-rpm tachometer, oil temperature, and volts. It also features a Retro Sound radio with upgraded speakers. For added comfort, Vintage AC was professionally installed.

The restoration began with the body being separated from the frame and entrusted to a professional body shop for extensive metalwork and panel replacement, all supported by detailed receipts. Replacement components include both full quarter panels, a bare driver-side door shell, radiator support, rear window and trunk filler panel, right inner fender well, front dash assembly, and a trunk floor section, sourced from Original Parts Group and other reputable restoration suppliers. Following the completion of the bodywork, the Chevelle was refinished in its factory-correct Marina Blue using a modern base coat/clear coat system, delivering exceptional depth and shine. Exterior trim has been professionally polished, while new chrome front and rear bumpers, headlights, taillights, and windshield further enhance the car's fresh appearance.

Prior to the drivetrain installation, the frame was separated from the body, media blasted to bare metal and reinforced with full-length 1/8-inch steel boxing plates to increase chassis rigidity and durability. The undercarriage reflects the quality of the build, presenting with a clean, black-coated floor pan, no visible rust, no fluid leaks, and neatly routed fuel and brake lines throughout. Fuel delivery is managed by an Aeromotive Phantom in-tank fuel system feeding the injectors through stainless steel fuel lines. Engine temperatures are controlled by a Griffin heavy-duty aluminum radiator paired with an electric cooling fan programmed to cycle automatically at 170 degrees. Additional attention was given to comfort and drivability with DEI heat shielding installed along the floor and transmission tunnel, while Boom Mat insulation helps reduce both heat transfer and road noise for a more refined driving experience.

The chassis is equipped with a comprehensive suspension system from Classic Performance Products (CPP), delivering modern handling without sacrificing the Chevelle's classic character. Up front, CPP round-tube control arms are paired with C6 Corvette spindles, a 1-inch lowered spring setup, and a CPP power steering gearbox for improved steering response and road feel. Out back, a CPP rear suspension system supports the Moser rear axle, providing strength and stability. Braking performance has been significantly upgraded with 13-inch four-wheel disc brakes, a CPP power brake booster and master cylinder kit, and heavy-duty CPP sway bars at both the front and rear to enhance cornering confidence. Completing the system, all factory rubber brake lines have been replaced with precision-bent stainless steel hard lines, ensuring long-term durability, reliability, and a clean undercarriage appearance.

Power comes from a 6.0-liter LS-based cast iron V8 sourced with approximately 40,000 miles. Before assembly, the engine was completely disassembled and inspected, revealing factory crosshatch marks still visible in the cylinder walls, a strong indication of minimal wear. The engine was then rebuilt with brand-new GM LS3 aluminum cylinder heads featuring new valves and valve springs, along with an LS3 intake manifold, factory fuel injectors, and ignition coils. Airflow is enhanced by a FAST 90mm Big Mouth cable-operated throttle body fed by a K&N cold air intake, while MSD ignition components ensure reliable spark. Engine management is handled by a FAST EFI system that currently operates on a base calibration. The system starts and runs well but will benefit from a final chassis dyno tune to optimize the fuel and ignition maps, as evidenced by a slight idle surge. Backing the LS powerplant is a T56 six-speed manual transmission equipped with a hydraulic throwout bearing, sending power through a custom Dynotech DOM steel driveshaft measuring 3.5 inches in diameter with a .083-inch wall thickness. The driveshaft has been high-speed balanced specifically for the T56 output shaft and connects to a Moser Ford 9-inch rear axle built with Chevelle-specific brackets, a Posi differential, and aggressive 4.11:1 gears. Exhaust duties are handled by JEGS ceramic-coated LS swap headers feeding a custom 2-inch dual exhaust system that exits through polished side-exit tips, giving the Chevelle an unmistakable muscle car sound to match its modern performance.
