The 1990s were an interesting time for pickups and SUVs. In the early 1990s, the EPA's tightening emissions and fuel economy restrictions -- meant to drive manufacturers to build more fuel efficient cars -- backfired. Rather than spend the money to engineer better cars, manufacturers made trucks more car-like. That sold more trucks, which got manufacturers fuel and emissions credits, but led to the "replacement" of the last, real C/K-Series Silverado with the gentrified, Silverado-branded pickup in 1999.
The base engine in this truck was the 4.3-liter V-6, which produced 200 horsepower at 4,400 rpm and 255 foot-pounds of torque at 2,800 rpm. The upgrade 5.0-liter small-block V-8 made 230 horsepower at 4,600 rpm and 285 foot-pounds of torque at 2,800 rpm. The top-dog 5.7-liter V-8 made 255 horses at 4,600 rpm and 330 foot-pounds of torque at 2,800 rpm. For heavy haulers, GM offered a 6.5-liter diesel making 180 horses at 3,400 rpm and 360 foot-pounds of torque at 1,800 rpm.
