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.
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.

As GM has periodically redesigned its civilian trucks and SUVs since 2001, LSSVs have also been updated cosmetically.
In April 1994, General Motors rejected a government request to issue a recall for all 1973–1987 C/K pickup trucks, claiming that it would involve over 6 million vehicles at a cost of over $1 billion. [78] As of 2020, such a recall would have been the third-largest ever (in terms of size). [89]

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 ...
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).
