Before the SS, the SSR, or the HHR, there was the 454SS. Chevy built 16,953 of these trucks in its first year, 1990, and just 3,205 from 1991-1993. All had the big throttle-body injected 454 engine, Bilstein gas-filled shock obsorbers, a bigger front sway bar, fast-ratio steering gear assembly, and other special bits. but the later years are the ones to get. 1990 models had 230 horsepower and 385 lb-ft of torque, while subsequent years were blessed with 255 and 405, respectively. The three-speed TH400 was replaced with a four-speed auto for more relaxed highway driving. A tachometer was also added. Despite the lopsided production figures and technological inferiority, undriven 1990s frequently list for $25,000 on eBay. I don't understand cars sometimes.
Motor Trend tested these at 15.8 seconds in the quarter mile, with a 0-60 time in the mid 7s, about the same as a 225-horsepower 1991 Mustang GT. They handled well for a truck - even better than their full-sized, 454-packing muscle-car forefathers (which isn't an accolade to be proud of). They may never appreciate the way the GMC Typhoon/Syclone surely will, but the torque rush from the big-block V8 is special in its own way. Special, like a barbed-wire tattoo.
PhiLOL actually likes the tuna here, but abhors structural rust. Save the manuals.
