To create the 1990-1991 Chevrolet 454 SS, Chevrolet plucked its big-block V-8 from the heavy-duty-truck line, stuffed it into a short-box C1500 Sportside pickup, stirred in performance goodies, and colored the creation in mean Onyx Black.
Thus emerged an understated sleeper of a pickup, a relatively lightweight two-whee-drive half-ton packing a monster 7.4-liter V-8 -- that's 454 cubic inches.
Although the V-8 produced only 230 horsepower, its strong suit was torque: 385 lbs/ft of it at a mere 1600 rpm -- the kind of grinding force that resulted in 0-60 mph in under eight seconds, which was Ford Mustang GT territory at the time.
Remarkably, the whole package cost only $18,295, including Bilstein shocks, quick-ratio steering, heavy front anti-roll bar, and beefy 275/60R15 tires on styled chrome wheels. Separate coolers were added for engine oil and transmission fluid, while a heavy-duty radiator kept the V-8 comfortable.
Luxury abounded, too: Silverado trim with Garnet Red cloth reclining high-back bucket seats; standard air, tilt, cruise, and tint; cassette stereo with equalizer; sliding rear window; power locks and windows.
Though rear beds warned the unwary to "beware the red bowtie," the beast looked quite ordinary otherwise. Only a blackout grille and six-slot chrome wheels suggested high performance.
Though its ride was jouncy, the SS handled with great agility for a truck. At highway speeds it was a screamer.
For 1991 a "more civilized" 454 SS came out, with four-speed electronic automatic transmission, 25 more horsepower, and even higher torque: 405 lbs/ft at 2400 rpm.
The rear-axle ratio was lowered to 4.10:1 for extra jolt off the line. On the dash was a tachometer, oddly omitted from 1990 models.
