This 1966 Chevrolet Chevelle 300 Deluxe two-door sedan underwent a reported five-year build, completed in June 2026, that included installing a 427ci V8 and a Tremec six-speed manual transmission. The body was repainted in metallic silver with a black hood stripe, and the cabin was retrofitted with red vinyl upholstery, air conditioning, Classic Instruments gauges, and an Alpine Bluetooth receiver. Further equipment includes a COMP camshaft, a Weiand intake manifold, exhaust headers, adjustable rear coilovers, Heidts spindles, Rally-style wheels, power steering, and front disc brakes. This modified Chevelle 300 Deluxe is now offered with a clean Colorado title in the seller’s name.
The car was repainted in metallic silver with a black hood stripe during the build, and the seller tells us the body was removed from the frame and the exterior trim and glass were also replaced. Details include tinted windows, chrome side mirrors, and quarter vent windows.
Painted Rally-style wheels wear chrome hubcaps and trim rings, and they are mounted with Mastercraft Avenger GT tires. The seller states that a Turn One steering box has been installed along with Heidts spindles, lowering springs, and Hotchkis sway bars. Braking is handled front discs and oversized rear drums, per the seller.
The front bucket and rear bench seats are upholstered in red vinyl, and engine-turned trim accents the dashboard. Appointments include an Alpine Bluetooth receiver, an 8-ball shift knob, aftermarket air conditioning, and a color-keyed headliner and carpets.
The tilting two-spoke steering wheel fronts a Classic Instruments 140-mph speedometer, tachometer, and supplementary gauges. The odometer shows 7k miles, and the seller states that approximately 5,300 miles have been added since the build was completed. Total mileage is unknown.
The engine is a 427ci V8 that utilizes a 454 block, a 366 crankshaft, forged steel heads, and aftermarket pistons, according to the seller. It is also equipped with a COMP camshaft, a Fluidampr harmonic balancer, a Weiand Street Warrior intake manifold, and a BeCool aluminum radiator with an electric fan.
The seller tells us the Tremec six-speed manual transmission was sourced from a Dodge Viper and has been fitted with high-performance components, and the 12-bolt rear axle has a limited-slip differential and 4.11:1 gears. The body mounts are said to have been replaced during the build, and the frame received a sealer and epoxy finish.
