Chevrolet built 13,748 examples of the 1990 454 SS, a regular-cab, short-bed half-ton pickup with a 7.4-liter big-block V8. For that first year, buyers got one paint color: Onyx Black. Red cloth buckets and red-and-silver trim set it off, but the body itself was always black.

The truck rode on Chevrolet’s GMT400 pickup platform. As RM Sotheby’s once put it, Chevrolet “plucked its big-block V-8 from the heavy-duty-truck line” for it. The result was a half-ton with heavy-duty power and a sport suspension.

Here is what went into it, how the numbers changed after 1990 and what one sells for today.

13,748 trucks in the first year

The production figure is on the record at the Savoy Automobile Museum, which owns a 1990 C1500 454 SS and lists “No. produced: 13,748.” GM Authority’s 2015 look at the truck gives the same number. It says Chevrolet built 13,748 in the maiden year “due to the buzz.”

After that, demand fell off sharply. GM Authority counts an additional 3,205 trucks from 1991 to 1993. In other words, the 1990 model year accounts for roughly four out of every five 454 SS pickups Chevrolet built.

Why every 1990 454 SS was black

Chevrolet kept the first-year truck simple. According to Aldan American’s history of the 454 SS, Onyx Black was the only color for 1990. Summit White joined the list for 1991, and Victory Red followed for 1992. A later PCARMARKET sale listing for a 1990 truck likewise calls Onyx Black “the sole color offered for the 1990 model year.”

The Savoy’s own truck fits that pattern. The museum describes it with an “Onyx Black body with silver and red accents and Garnet interior.” Meanwhile, Aldan American lists red cloth high-back sport buckets, a center console and an AM-FM cassette stereo inside. Outside, it adds tinted glass and halogen composite headlamps.

The big-block and the hardware

Power came from the L19 7.4-liter, or 454-cubic-inch, V8. Aldan American rates it at 230 horsepower and 385 lb-ft of torque for 1990. A three-speed automatic sent that torque to a locking rear differential with 3.73 gears.

The chassis got attention, too. Aldan American lists the ZQ8 Sport suspension with Bilstein gas shocks, plus low-profile blackwall tires. The Savoy, in addition, gives a 117-inch wheelbase and a weight of 4,662 pounds for its truck. It also lists air conditioning, cruise control, anti-lock brakes and a stereo with a graphic equalizer.

For all that, the 454 SS was not especially quick. GM Authority puts its quarter-mile times in the “high-15s at best.” It also quotes fuel economy of 10 mpg in the city and 11 on the highway.

What changed after 1990

Chevrolet kept updating the truck. According to GM Authority, the truck gained another 25 horsepower for 1991, and the transmission got another gear. Still, GM Authority says those changes “did little to help,” and sales never came close to the first year again.

A recent Jalopnik history of early muscle trucks fills in the details. It puts the later output at 255 horsepower and 405 lb-ft of torque. It also says a four-speed automatic replaced the three-speed about a year after launch. At the same time, later four-speed trucks got a 4.10 rear axle in place of the 3.73.

Those changes showed up in the numbers. Citing Car and Driver, Jalopnik lists 7.1 seconds from 0 to 60 mph for a four-speed truck. The Savoy, for its part, gives the 454 SS a top speed of 120 mph.

Ford answered later. Jalopnik notes that the 1993 SVT Lightning used a 5.8-liter V8 with 240 horsepower and 340 lb-ft. By comparison, that was 10 horsepower more than the 1990 Chevy but 45 lb-ft less torque. In the end, Chevrolet sold the 454 SS through 1993, according to both Jalopnik and GM Authority.

The price climbed as well. Both the Savoy and Aldan American give a 1990 original price of $18,295. Aldan American adds that prices rose in later years, along with horsepower.

What a 1990 454 SS brings today

At least one low-mileage first-year truck has sold far above that sticker. GM Authority reported that a 1990 454 SS in Onyx Black with 750 miles sold on Bring a Trailer for $91,500 on September 8, 2026. According to the same report, the truck had cost $18,845 new at Kevin Whitaker Chevrolet in Newberry, South Carolina.
