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

If you're looking to build a seriously powerful Duramax diesel, starting with a robust long block is the way to go. This Industrial Injection Race Performance Long Block is built for the 2006-2007 Chevrolet Silverado and GMC Sierra trucks equipped with the LBZ Duramax engine. It's a solid foundation for a high-performance build, whether you're aiming for more towing power, faster acceleration, or a dedicated race truck.

Industrial Injection takes a carefully selected LBZ engine core and rebuilds it with performance in mind. This long block includes a set of ARP head studs, which are a critical upgrade for any engine that will see increased boost pressure. ARP studs offer a much stronger clamping force than the factory bolts, helping to prevent head gasket issues under demanding conditions. The engine is assembled with attention to detail, ensuring all components are within specification for reliable operation. This is a well-built unit designed to handle more power than a stock engine.

This long block comes as a complete engine assembly from the crankshaft up to the cylinder heads, including the block, crankshaft, connecting rods, pistons, rings, bearings, camshaft, lifters, pushrods, and cylinder heads. It does not include the fuel system, turbocharger, intake manifold, or accessories, so you'll need to transfer those from your original engine or purchase them separately. Please note that this engine is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and break-in procedures.
