Industrial Injection 00-04 Chevrolet LB7 Duramax Race Performance Long Block (w/ Arp Studs)

Starting with ARP head studs, this Industrial Injection race performance long block is built for the demanding needs of your 2004-2005 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD. This isn't just a replacement engine; it's a significant upgrade designed to handle increased power and stress, making it a solid choice for those looking to push their Duramax LB7 beyond stock capabilities.

Industrial Injection has assembled this long block with performance in mind. The core components are carefully selected and machined to meet strict tolerances, ensuring reliability even under heavy load. The inclusion of ARP head studs is a notable detail, as they offer superior clamping force compared to factory fasteners, which is crucial for maintaining head gasket integrity when you're running higher boost pressures or more aggressive tuning. This attention to detail in the build process means you're getting an engine that's ready to perform and endure.

When you're investing in a performance long block like this, you're looking for confidence in your build. This engine comes as a long block, meaning the critical internal components like the block, crankshaft, connecting rods, pistons, camshaft, and cylinder heads are assembled and ready to go. You will need to transfer or purchase additional components such as the fuel system, turbocharger, intake and exhaust manifolds, and accessories to complete the installation. This approach allows for customization and ensures you can pair the engine with the specific performance parts that match your goals. Please note that this engine is not CARB approved and cannot be shipped to California.
