During the latter years of production, 379-and-432-cubic-inch (6.2 and 7.1 L) versions with enlarged crankshaft journals were manufactured as well. GMC produced a 637-cubic-inch (10.4 L) 60° V8 with a single camshaft using the same general layout (bore and stroke) as the 478 V6. The 637 V8 was the largest-displacement production gasoline V8 ...
6.2L fitted to a 1987 HMMWV. The original 6.2 L (379 cu in) diesel V8 was introduced in 1982 for the Chevrolet C/K and was produced until 1993. The 6.2L diesel emerged as a high-fuel-economy alternative to the V8 gasoline engine lineup, and achieved better mileage than Chevrolet's 4.3L V6 gasoline engine of the 1980s, at a time when the market was focused on power rather than efficiency.
They used Pontiac's 347-cubic-inch (5.7 L) in 1957. For 1958, GMC reduced the bore of Pontiac's 370-cubic-inch (6.1 L) to 3.875 in (98.4 mm), resulting in a displacement of 336-cubic-inch (5.5 L). (In Canada, however, GMC used the Chevrolet small-block engine rather than the Pontiac.) For 1959, as the Pontiac engine's stroke was lengthened to 3 ...
1967–1972 GMC Truck 60-degree V8 (derived from the GMC 60-degree V6) 1967–1984 Cadillac New V8; 1969–1984 Holden 253; 1969–2000 Holden 308 (stroke reduced in 1985, making it 304 cu in (5.0 L); 350 cu in (5.7 L) version also produced from mid 1994 for use by HSV) 1982–1995 Cadillac HT
The 6.6L Duramax diesel engine (VIN code "L") is used on 2010 interim and 2011 Chevrolet Express and GMC Savana vans and 2011 Chevrolet Silverado/GMC Sierra HD trucks with RPO ZW9 (chassis cabs or trucks with pickup box delete). The LGH engine is rated at 335 bhp (250 kW) at 3,100 rpm and 685 lb⋅ft (929 N⋅m) at 1,600 rpm.
Shared with C/K pickup trucks, a 4.3 L V6 was standard, while 5.0 L, 5.7 L, 6.5 L turbo-diesel, and 7.4 L V8s were options. [5] All gasoline engines adopted the "Vortec" port-fuel injection upgrades for 1996, increasing power and torque outputs; the 6.5 L turbo-diesel was offered in a GM full-size van for the first time.
The 6.0 L is a larger version of the LS engine. 6.0 L blocks were cast of iron, designed to bridge the gap between the new small blocks and big blocks in truck applications. There were two versions of this engine: LQ4 and LQ9, the latter being more performance oriented.
The previous (for 2001 only) C3 model of the GMC Sierra trucks were renamed Denali in late 2001 as a 2002 model. The 2002–2004 Sierra Denali was equipped standard with a 325 hp 6.0 L V8, all-wheel-drive, and Quadrasteer, the 4-wheel steering system developed by General Motors. No 5.3 L V8 option was offered (until the 2014 model year with the ...
