GM marketed its big pickups in parallel Chevrolet and GMC lines, the latter called Sierra. A 160-horsepower 4.3-liter V-6 was standard for most 1500/2500 models. All offered two gas V-8 options: a 5.0-liter with 175 horsepower and a 5.7-liter with 210. The 7.4 V-8 was optional and made 230 horsepower, 255 in the 454SS. A 140-horsepower 6.2-liter diesel V-8 was optional except for SS, W/T and short bed 1500s. 1992’s new turbocharged 6.5-liter diesel V-8 had 190 horsepower and was available in heavy-duty 2500s and regular-cab 3500s. GM said it was virtually free of the visible exhaust smoke typical of diesels.
GM’s full-size pickups long battled Ford’s F-Seriesas America’s best-selling vehicle line. Ford beat Chevrolet for the 10th consecutive year in calendar 1991, but GM has often won if GMC sales were included. No matter. These rivals were closely matched, so your choice likely came down to personal preference and the kind of deal you could get.
