The 2008 Chevrolet Silverado 2500 comes equipped with a 6.0L Vortec V8 engine (RPO code LY6). This naturally aspirated, iron-block engine produces 353 horsepower and 383 lb-ft of torque. It features aluminum cylinder heads, sequential fuel injection, and Active Fuel Management technology that deactivates four cylinders under light load conditions to improve fuel economy. The engine uses a coil-on-plug ignition system and is designed for heavy-duty applications including towing and hauling. This powerplant is paired with either a 6L90E six-speed automatic transmission or a manual transmission depending on configuration.

The 2008 Silverado 2500 shares most parts with 2007-2010 model years of the same generation. Engine components from the 6.0L Vortec are compatible across 2007-2013 models that used the same LY6 engine code. Body panels, interior components, and electrical parts typically interchange with 2007-2010 models. The 6L90E transmission parts are compatible with 2007-2010 heavy-duty trucks. Suspension components may fit 2007-2010 2500/3500 series trucks. However, always verify part numbers and RPO codes as GM made running changes throughout production years that can affect compatibility.

The 6.0L Vortec V8 is generally a robust and reliable engine when properly maintained, but it has some notable weaknesses. The Active Fuel Management system is the biggest concern, with lifter failures being common and potentially catastrophic. Regular oil changes with quality oil are critical for longevity. The iron block construction makes it durable for heavy-duty use, and many examples exceed 200,000 miles with proper care. Intake manifold gaskets and fuel pumps are wear items that require attention at higher mileages. Overall, it’s a capable workhorse engine that responds well to preventive maintenance but requires attention to known problem areas.
