Chevrolet Performance 6.2L 376 L92 Remanufactured Long Block Crate Engine – 19418398

The Premium 6.2L LS Crate Engine for Your Performance Build

The Chevrolet Performance 6.2L 376 L92 remanufactured long block crate engine provides a high-quality foundation for your LS project. This Gen IV 6.2L/376 cubic inch V8 is built on the L92 platform—the same engine family that powered Cadillac Escalade and other GM trucks and SUVs from 2006-2010 —and is designed for builders who want to finish their engine their way, with their own choice of intake manifold, fuel system, ignition, and accessories .

As part of our extensive LS Engines collection, this remanufactured long block combines Chevrolet Performance’s engineering excellence with a cost-effective approach. The all-aluminum construction, 1-piece rear main seal, and factory-quality remanufacturing make this an ideal starting point for performance builds that demand the legendary LS foundation .

What Makes the 6.2L L92 Long Block a Smart Foundation for LS Builds?

The 6.2L L92 engine represents the pinnacle of GM’s Gen IV small-block development. This engine family was used extensively in 2006-2010 Cadillac Escalade models , where it demonstrated its durability and impressive power potential. The L92 platform features:

• All-aluminum construction for excellent power-to-weight ratio 

• L92-style cylinder heads with large rectangular ports for outstanding airflow

• 6-bolt, cross-bolted main caps for exceptional bottom-end strength 

• Hydraulic roller camshaft with OE roller lifters 

L92 vs LS3 – Understanding the Difference

The L92 and LS3 are closely related Gen IV 6.2L engines. Both share the same 4.065-inch bore and 3.622-inch stroke (376 cubic inches) and feature aluminum blocks and heads. The key difference lies in the cylinder head castings: L92 heads were originally designed for truck and SUV applications, while LS3 heads were developed for the Corvette and Camaro.

The remanufactured L92 long block (19418398) is an excellent alternative to more expensive LS3 crate engines, offering the same 6.2L displacement and robust architecture at a more accessible price point.
