The GM LS6 motor represents two generations of high-performance GM V8 engineering, with the classic 5.7L LS6 and the modern 6.7L Next-Gen LS6 sharing the same performance-focused name but using different engine architectures. The 5.7L Gen III LS6, produced from 2001 to 2005, was developed as a more powerful version of the LS1 and featured a lightweight aluminum block, high-flow cylinder heads, revised intake and camshaft technology, and a 6,500-rpm redline. It produced 385 hp in 2001 and up to 405 hp in later versions, making it a standout engine in the Chevrolet Corvette Z06 and Cadillac CTS-V.
The new 6.7L LS6, introduced for the 2027 Chevrolet Corvette, takes the LS6 name into GM’s next-generation small-block family with 535 hp, 520 lb-ft of torque, 13.0:1 compression, a 103.25 mm bore, and 100 mm stroke. Designed as a naturally aspirated performance engine, it uses a 95-mm throttle body and tunnel-ram-style intake system to support strong airflow and high-output performance, making the modern LS6 a powerful option for enthusiasts seeking responsive, naturally aspirated V8 performance.
2001–2004 Chevrolet Corvette C5 Z06
The 2001–2004 Chevrolet Corvette C5 Z06 was powered by the high-performance 5.7L LS6 V8, producing 385 hp in 2001 and 405 hp from 2002–2004. Its lightweight construction, high-flow cylinder heads, and high-revving design helped make the C5 Z06 one of the most capable American performance cars of its era.
2004–2005 Cadillac CTS-V
The 2004–2005 Cadillac CTS-V used the 5.7L LS6 V8, producing approximately 400 hp and 395 lb-ft of torque. Combined with rear-wheel drive and a six-speed manual transmission, the LS6 gave the CTS-V strong acceleration while maintaining the comfort and practicality of a luxury sport sedan.
LS6 Engine for Performance Builds
