This 1958 Chevrolet Impala coupe is a triple-carbureted example that is said to have been sold new in Seattle, Washington, and to have developed a cracked engine block that resulted in the car being parked during the 1970s.

This 1958 Chevrolet Impala coupe is a triple-carbureted example that is said to have been sold new in Seattle, Washington, and to have developed a cracked engine block that resulted in the car being parked during the 1970s. A replacement short block was purchased through Chevrolet, but its installation remained uncompleted prior to the car’s acquisition by the current owner in 2009. A subsequent recommissioning of the vehicle included rebuilding the engine, the carburetors, and the fuel pump; recoring the radiator; refreshing the brakes; and replacing the heater core, the fuel tank, and the dual exhaust system. The car is finished in yellow over gray and green cloth and vinyl upholstery, and equipment includes power brakes, a heater/defroster, and a push-button AM radio.
The body is finished in Colonial Cream (925A) with styling cues that include fender-top hood ornaments, quad headlights and parking lamps, backslash C-pillars, wrap-around glass, full-length side spears, a faux roof vent, canted tail fins, triple taillight groupings, and 16 vertical chrome accents in four sets of four. Penetrating rust has occurred in the headlight eyebrows, the hood, the upper inside passenger door, the passenger-side floorboard just inside the doorsill, the lower fenders, the trunk lip, and the floor of the trunk. A refinished replacement trunk lid has been fitted and the original trunk lid and a spare hood and front fenders are included in the sale.
Silver-painted 14″ wheels are fitted with Kingstar Radial H714 whitewall tires showing 2009 date codes. A refresh of the brakes in 2016 included rebuilding the Treadle Vac master cylinder booster and replacing the adjustment access hole covers and both front wheel cylinders.
The seats—which are trimmed in green metallic vinyl with tri-tone fabric inserts (815)—display separated seams, and wear is noted on the matching dash pad, door panels, and carpeting.
A two-tone steering wheel with a full horn ring fronts a horizontal-sweep 120-mph speedometer and gauges for coolant temperature and fuel level. The five-digit odometer shows 90k miles, approximately 2k of which were added by the owner; true mileage is unknown. The speedometer cable and the coolant-temperature sender were replaced in summer 2021.
The replacement 348ci Super Turbo-Thrust V8 is equipped with a trio of two-barrel Rochester G carburetors said to have been taken off of the original engine and a solid-lifter camshaft with a “Duntov” grind performed at Cam Grinders of Seattle, Washington, in 2011. Refreshing the engine in 2009 included resizing and aligning the connecting rods, balancing the rotating assembly, rebuilding the carburetors and the fuel pump, installing hardened valve seats, and replacing the bearings, the piston rings, and the water pump. The fluids were serviced within the past year.
Gases exit by way of a dual exhaust system that has been replaced from the collectors back. Power is sent to the rear wheels through a Turboglide three-speed automatic transmission that was rebuilt by the owner with a reconditioned modulator valve and replacement plates, seals, and gaskets sourced through Fatsco Transmission Parts of Pine Brook, New Jersey.
The owner’s records, a spare hood and front fenders, the original trunk lid, a hubcap, an original-type hydraulic camshaft, an oil pan, and assorted smaller parts will accompany the car. The year-of-manufacture license plates pictured on the vehicle are not included, but two more sets including one from 1963 are.
