Chevy Chevrolet Corvette Engine 5.7 V8

This is a used Chevrolet LS1 5.7-liter V8, GM part number 12550592, pulled from a Corvette C5. The LS1 uses an aluminum block and heads for a lighter, high-revving small-block, originally rated at roughly 345 hp at 5,600 rpm, and is a common choice for LS-swap builders working on muscle cars, hot rods, trucks, and drift cars.

Where this engine came from

GM used this LS1, part number 12550592, in the 1997-2004 Corvette C5, with closely related versions also found in the Camaro SS and Firebird WS6 of the same era, allowing for slight variations between applications. Displacement is 5.7 liters, or 346 cubic inches, running on gasoline.

Condition and shipping

This engine has been compression tested and inspected, and ships in a secure crate from the USA. A warranty is available on this particular engine; ask us for the current terms before you order. Given that this is a used take-out rather than a new crate engine, plan on a visual inspection of wiring connectors and accessory brackets once it arrives, since LS1 pulls can vary slightly between the Corvette and F-body applications it came from.

Q: Will this work as a direct LS1 swap? It is built to the same part number used in the Corvette C5, Camaro SS, and Firebird WS6, allowing for some variation between those applications, so confirm your specific mounts and wiring before ordering.
