The 1958 Chevrolet Impala marked a significant departure in styling for the iconic nameplate, introducing a longer, lower, and wider design that captured the flamboyant spirit of the late 1950s. Its single-year body style, characterized by distinctive hooded headlights, a bold grille, and dramatic rear fender “bat wings,” has cemented its place as a true automotive icon. While originally offered with a range of engines, the example presented here boasts a significant upgrade, transforming this stylish cruiser into a formidable performance machine.
Repainted History: Originally finished in the alluring Tropic Turquoise, this 1958 Chevrolet Impala two-door Sport Coupe underwent a repaint in a classic brown and white combination in the early 1980s. This refreshed exterior still showcases the car’s iconic design elements, including the deeply hooded headlights that lend a mysterious air to the front end, dual chrome side mirrors adding a touch of elegance, and dual exhaust outlets hinting at the power within. The bright chrome window surrounds, bumpers, and trim accentuate the car’s sleek lines. It’s worth noting that some paint imperfections are present, and a rust spot can be observed near the back of the left rear wheel well, signs of its age and journey.
Rolling Stock and Stopping Power: This Impala rides on a set of 15″ wire wheels, a stylish choice that complements its vintage aesthetic. The wheels are wrapped in Duralo tires with a 215/65 profile, providing a good balance of grip and ride comfort. Significantly, the car has been upgraded with disc brakes at all four corners, offering a substantial improvement in stopping power compared to the original drum brake setup, enhancing safety and driver confidence.
Interior Comfort and Classic Touches: Inside, the cabin features a split-folding front bench seat that has been reupholstered in an attractive two-tone brown cloth and vinyl. This provides comfortable seating for occupants. Classic interior appointments include a convenient rear center armrest for rear passengers, safety-minded lap belts, and traditional wind-up windows. While the aftermarket radio and tape player are currently not functioning, the interior retains its vintage charm and offers a glimpse into the driving experience of the late 1950s.
Instrumentation and Mileage: The classic two-spoke steering wheel, complete with a chrome horn ring, fronts the instrument cluster. This includes an inoperative 120-mph speedometer and gauges for monitoring coolant temperature and fuel level. Adding to the driver’s awareness are a trio of aftermarket auxiliary gauges mounted neatly underneath the dashboard. The five-digit odometer currently displays 28k miles, with approximately 500 miles added by the current owner. However, the total mileage of the vehicle remains unknown.
Engine and Performance Powerhouse: The heart of this 1958 Chevrolet Impala has been significantly enhanced. The original small-block V8 was rebuilt and enlarged to a potent 408 cubic inches in 2021. The dynamometer results from this build showcase impressive maximum outputs of 311 horsepower and a substantial 425 lb-ft of torque. This enhanced performance is achieved through the installation of a Holley 600-cfm four-barrel carburetor equipped with an electric choke, an Edelbrock Performer intake manifold for improved airflow, free-flowing exhaust headers, and a high-efficiency aluminum radiator to keep things cool under pressure. This combination transforms the Impala from a stylish cruiser into a true performance machine.
Drivetrain Dynamics: Power from the formidable 408ci V8 is efficiently routed to the rear wheels through a reliable two-speed automatic transmission. According to the seller, both the transmission and the rear end were professionally rebuilt in 2021, ensuring smooth and dependable operation, capable of handling the increased power output.
Trim Tag Insights: Decoding the trim tag provides valuable information about the car’s original specifications. The style code “58-1847” confirms it as a 1958 Chevrolet Sport Coupe with two doors. The body code “K9474” indicates it was assembled at the Kansas City, Missouri, plant. The trim code “836” reveals the original interior scheme as Gray, Turquoise, and black. Lastly, the paint code “914A” confirms its original exterior color was the striking Tropic Turquoise.
