C5 Corvette engine

The C5 Corvette engine represents the pinnacle of late-’90s GM performance engineering. Built on the LS1 5.7L small-block V8 platform, it introduced an all-aluminum construction, advanced coil-near-plug ignition, and improved airflow design that transformed how enthusiasts viewed American sports cars. Producing 345 hp and 350 lb-ft of torque, the LS1 combined modern refinement with the raw character of the Corvette nameplate. Later C5 Z06 models featured the LS6 variant, refined to 405 hp / 400 lb-ft, offering even greater throttle response and high-RPM performance. Each used C5 Corvette engine from Tagore Auto Parts undergoes compression, leak-down, and performance testing to ensure smooth operation and lasting reliability.

1997–2000 LS1 Engine (Base Models)

From 1997 through 2000, base Corvette models used the LS1—a robust and responsive engine that set a new benchmark for performance. With 10.1:1 compression and advanced cylinder head design, it delivered crisp acceleration and a wide powerband. Whether you’re rebuilding a stock C5 or designing a custom street project, our used LS1 engines are carefully inspected and ready to install. Pair it with a tested Chevy Silverado 3500 engine or Toyota Corolla manual transmission for multi-platform performance swaps.

2001–2004 LS6 Engine (Z06 Models)

In 2001, the high-performance C5 Corvette Z06 introduced the LS6—a reengineered version of the LS1 featuring a more aggressive cam profile, revised cylinder heads, and freer-flowing intake and exhaust systems. Initially rated at 385 hp, the LS6 peaked at 405 hp and 400 lb-ft in 2002–2004 models. This engine’s power delivery and durability make it a favorite among tuners and racers. At Tagore Auto Parts, each used LS6 engine is verified for compression, oil pressure, and internal integrity, ensuring optimal performance for street or track applications.
