19433750 L8T Long Block


In addition to the complete L8T crate engine Chevrolet Performance offers the L8T Long Block — the high-output, direct-injected foundation of the Gen V Small Block-based 6.6L engine offered in the Silverado 2500HD and 3500HD models.

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.
