When Chevrolet unveiled the 454SS in 1990, it was a bold expression of muscle for the pickup world—a single-cab, short-bed rocket engineered with the heart of a big-block. Built to excite gearheads and truck lovers alike, the 454SS was an instant classic, arriving during a time when performance trucks were still a rarity. Featuring a 7.4L (454 cu in) V8 mated to a heavy-duty 3-speed Turbo Hydra-Matic 400 automatic transmission, the 454SS was more than just a workhorse—it was a boulevard bruiser.
This particular 1990 Chevrolet 454SS, finished in factory-correct WA8555 black over Garnet red interior (code 47I), is a time capsule example that showcases just 40,883 actual miles on the odometer. With its numbers-matching 454 engine and original TH400 transmission, it's a superb specimen of one of GM’s most aggressive truck offerings from the era. From the clean CarFax report to the meticulously documented service history, this example was clearly cherished throughout its life.
Originally sold and titled in California, the truck passed a string of emissions inspections dating back to 1995 and remained under careful ownership, as shown by its consistency in documentation. Mechanically, it’s reported to “run and drive extremely well” with performance matching expectations for such a low-mileage example.
Visually, the truck retains a bold and cohesive look with a complete repaint in its original black that presents beautifully. The 15-inch OE 454SS wheels are wrapped in brand-new BF Goodrich Radial T/A tires (275/60R15), coded 2025 for freshness, enhancing the aggressive stance. Complementing the clean exterior is an aftermarket tonneau cover with an electric release switch neatly integrated into the lower driver-side dash—a rare and convenient upgrade.
Under the hood, the engine bay appears stock and well-kept, with factory manifolds, crossover pipe, catalytic converters, and an aftermarket muffler feeding dual tailpipes. The aluminum radiator keeps things cool, while the power front disc brakes and rear drums ensure confident stopping. Power steering and a front sway bar make for surprisingly agile handling by 1990s truck standards.
Inside, the all-original Garnet interior is well-preserved and reflects the truck’s minimal use. The cabin includes factory gauges for temperature, oil pressure, and voltage, as well as working air conditioning (converted to R134A), tilt steering, intermittent wipers, and a JVC AM/FM USB auxiliary radio. Power windows and locks are fully operational, and the original bucket seats with a center console complete the classic SS experience. Even the LED dome light and bed cover button are in working order, further reflecting attention to detail.
The undercarriage is noted as solid and original, with only minor expected surface corrosion—no surprises here. Everything from the fuel and differential fluids to the battery charging system checked out in pre-sale inspections, making this one of the more mechanically sound examples to surface in recent memory.
In a world where so many 454SS trucks have been heavily modified or worn down by time, this one stands apart as a preserved and documented example with mileage, originality, and curb appeal to spare. It’s a shining example of how GM’s muscle truck legacy can age gracefully when given the right care.
