LS3 6.2 V8 – Chevrolet Corvette (C6), Camaro SS & HSV Head Gasket Keychain
This stainless-steel head gasket keychain celebrates the GM LS3, Chevrolet’s naturally aspirated 6.2-litre Gen IV small-block V8. First fitted to the 2008 Chevrolet Corvette, the LS3 combined an aluminium block, rectangular-port cylinder heads and 376 cubic inches of pushrod V8 performance.

Vehicle Compatibility Matrix
The LS3 should not be confused with the L99 Camaro automatic engine, which added Active Fuel Management and variable valve timing, or with the later direct-injection LT1.
Why This Engine Matters
The LS3 is one of the defining modern Chevrolet pushrod V8s because it delivered large-capacity naturally aspirated performance from a relatively compact and lightweight aluminium small-block package. It became the standard engine in the C6 Corvette and fifth-generation Camaro SS, two of Chevrolet’s most important modern performance cars.
Its rectangular-port L92-style cylinder heads, 10.7:1 compression ratio and hydraulic-roller camshaft give the factory LS3 strong airflow and a wide performance aftermarket. The engine’s absence of cylinder deactivation and variable valve timing in standard LS3 specification has also made it particularly recognisable among GM V8 enthusiasts.
Technical Specifications
Factory output varies by vehicle. Chevrolet Corvette LS3 versions were rated from 430 to 436 hp, while Camaro SS, Pontiac G8 GXP and Chevrolet SS calibrations differ by model year and exhaust system. The engine dimensions and core architecture above are drawn from Chevrolet Performance’s LS3 crate-engine technical specification, published on its New Zealand site in 2024.
