With 401 horsepower and 464 lb.-ft. of torque on tap, the L8T crate engine is the largest displacement LT-family engine in our lineup, offering plenty of low-rpm torque. Direct injection offers more precise fuel control than port injection, enabling a comparatively high compression ratio of 10.8:1 in the engine, which contributes to its high output.

It's built with a forged steel crankshaft and other high-strength parts. Additional features such as oil-spray cooling for the pistons and a cast iron, long-skirt cylinder block with six-bolt, cross-bolted main caps contribute to the engine's strength and durability. Comes with production style exhaust manifolds.

Our L8T Long Block includes the direct injection cylinder heads and coil-on-plug ignition system, as well as the oil pan with dipstick, but does not include the intake manifold, throttle body, engine-mounted high-pressure direct injection fuel pump or fuel injectors. All must be sourced separately to complete the engine assembly. Additionally, the Front End Accessory Drive system is not included. See Installation Notes for recommendations.
