1990 Chevy 454SS Sport Truck – 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. 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.
