"The LS-Series cylinder block is the foundation for the serious performance
achievements that are driving a new generation of street and racing enthusiasts.
Features include a deep-skirt casting (the block side extends below the
crankshaft centreline); 6-bolt cross-bolted main caps, strong and lightweight
aluminium alloy casting (most production blocks) and provisions for the latest
in engine control management. The cam-in-block configuration brings inherent
torque to every LS engine, with production-based blocks capable of supporting
combinations of 500 horsepower or more.
Whether you’re building a mild street engine or an Outlaw racing engine,
starting with a strong LS cylinder block brings the assurance that you’ll make
the power you need with a durable foundation.
