1991 Chevy 454SS Supercharged (30k Miles) – 7.4L V8, Auto w/OD, RWD, Whipple Supercharger (Dealer Installed), Tonneau, New Tires, Low Miles!1991 Chevy 454SS Supercharged (30k Miles) – The 454 SS arrived in late 1989 as a 1990 model, smack in the middle of the fourth-generation (GMT400) truck’s run. While the big-block engine beneath the hood was a primary selling point, the truck delivered more than just straight-line performance. Inside, all 454 SS pickups were based upon the quasi-luxury Silverado trim level, and came complete with amenities like cruise control, a tilt sport steering wheel, an AM/FM/cassette stereo with graphic equalizer, intermittent wipers, and bolstered sports seats for driver and passenger. Only short-bed, standard-cab C1500s were fitted with the 454 SS package (RPO B4U), and for the first two years on the market, the sole color choice was Onyx Black with a Garnet Red interior. The 454-cu.in. (7.4-liter) fuel-injected engine was not exclusive to the 454 SS model, but instead was the same V-8 available in 3500 and 2500 pickup models. In the sport truck’s debut year, the engine produced 230 horsepower and 385 pound-feet of torque, and sent this through a three-speed Turbo Hyda-Matic automatic transmission to a limited-slip differential with a 3.73:1 axle ratio. Maryland Public Television’s MotorWeek tested a 454 SS in late 1989, and found the truck capable of running from 0-60 mph in 7.7 seconds, completing the quarter-mile in 15.9 seconds at 87 mph. Thanks to the addition of a Performance Handling Package, which contained Bilstein shocks, a 1.25-inch front anti-roll bar and 12.7:1 ratio steering, the 454 SS was a capable handler as well, as long as one factored in the truck’s two-and-a-quarter-ton weight and high center of gravity. BFGoodrich supplied 275/60R-15 Comp T/A tires, and in conjunction with rear anti-lock brakes, the 454 SS proved capable of stopping from 60 mph in a very respectable 127 feet, a number also provided by Motor Week.
