LS6 Engine for Sale Australia – High Performance 5.7L V8 Upgrade for Holden & Custom Builds

Looking for a genuine LS6 engine for sale in Australia? The 5.7L LS6 V8 is one of the most respected high-performance naturally aspirated engines in the GM LS family. Originally developed for performance platforms like the Chevrolet Corvette Z06 and the Cadillac CTS-V, the LS6 is known for its improved airflow, higher compression ratio, and stronger internal components compared to the standard LS1.

If you’re upgrading a Holden Commodore, HSV, drift car, street machine, or custom project, the LS6 offers serious power potential with legendary LS reliability.

• Aluminum block and heads

• 10.5:1 compression ratio

• High-flow LS6 intake manifold
