Lot #670 - This 1990 Chevrolet Silverado 454 SS pickup is well-equipped for a cruising experience, with options and amenities that include power brakes and power steering, factory air conditioning, power locks and windows, plus a lower-restriction dual exhaust. Riding on a brand-new set of BFGoodrich tires, this example is accompanied by a clean CARFAX. Following the landmark redesign of Chevrolet's pickup truck lines for 1988, the GM division's engineers quietly developed RPO (Regular Production Option) B4U to unleash the Silverado 454 SS in late 1989 for a 1990-model-year launch. No mere decal-and-stripe special, the 454 SS was a fully integrated performance and appearance package for the Silverado with menacing looks, high-end amenities and electrifying performance. Available only in regular-cab, short-bed form, the 454 SS was offered in any color you wanted, as long as it was Onyx Black. True to its name, the 454 SS featured Chevrolet's fuel-injected 454ci V8 engine, developing a factory-rated 230hp engine mated to a Turbo-Hydramatic 3-speed automatic transmission. Its peak torque of 385 ft/lbs arrives at just 1,900 engine revolutions. Other choice 454 SS features included a 3.73 limited-slip rear axle, Performance Handling Package and Bilstein gas shocks, plus a heavy-duty radiator, quick-ratio steering, a front anti-roll bar and 275/65 R15 tires. Passenger amenities were many, including a Garnet Red interior with high-back cloth bucket seats and a center console, AM/FM stereo with cassette payer and graphic equalizer, and tilt steering. Performance backed up the pickup's image, including 0-60 acceleration in 7.7 seconds and a 15.9-second quarter-mile at 87 mph, plus good handling and braking. Production was relatively low, with select updates through 1993, with experts reporting 16,953 built in all.
