and improved fuel mixture distribution. The 5.7 liter V8 also had new heavy-duty intake valves and powdered metal camshaft sprockets. Standard on all engines was a lighter more powerful 100-amp CS130 alternator. (All power and torque figures are pulled from GM factory service manual) 1973–1980 Blazers used the gear-driven part-time NP-205 transfer case (mostly mated to the SM465 manual transmission and some TH350s) or the chain-driven full-time NP-203 transfer case (mated to the TH350 automatic) and DANA-44 front/12-bolt rear axle combination through 1980. Starting in 1981 used the chain-driven NP208 transfer case (NP241 after 1988) with front 10-bolt/rear 10-bolt axle combinations until 1991. There is an overlap of 12-bolt rears into the early 1980s, while the 10-bolt front axle was phased into production in the late 1970s. 1992–1994 In 1991, for the 1992 models, GM redesigned its large SUVs, moving to the GMT400 architecture that had debuted for GM's 1988 pickup lines. Dimensions grew modestly with a wheelbase and length overall. The Chevrolet was now called the Full-Size Blazer, dropping the 'K5' prefix. The GMC Jimmy was renamed, and straightaway launched as the first generation GMC Yukon, while the smaller S15 Jimmy dropped the prefix and was named the 'Jimmy' from then on. Unlike prior generations, the GMT400-based Blazer/Yukon did not have a removable roof, and the tailgate glass was fixed. The Blazer was named "Four Wheeler of the Year" in 1992 by Four Wheeler magazine. The standard engine remained the small-block V8 with throttle-body fuel injection. A 6.5 L turbocharged Detroit Diesel V8 was added as an option for 1994, with output of and of torque. The diesel engine was available only with a four-speed automatic transmission. All versions were fitted with an independent front suspension and solid rear axle with leaf springs; four-wheel drive versions had torsion springs in front, while two-wheel drive versions had coil springs. In 1995, the Blazer nameplate was discontinued for the full-size vehicle; it was renamed and relaunched as the new 1995 Chevrolet Tahoe. The 1995 Tahoe/Yukon also included a longer wheelbase, four-door wagon body style which was smaller than the Suburban but larger than the two-door Tahoe. From then on, the Tahoe and Yukon models were offered in two sizes, as two- and four-doors. At the same time, Chevrolet rebranded their 2nd generation successor to the S-10 Blazer, and the Blazer name was transferred to it as Chevy's 'all-new Blazer' (and GMC
