The LS7 7.0L 427ci 505 HP Crate Engine delivers legendary naturally aspirated Chevrolet Performance power with high-RPM capability and race-inspired engineering.
Originally developed for the C6 Corvette Z06 and later used in the fifth-generation Camaro Z/28, this LS7 crate engine is the largest-displacement Gen IV small-block production engine from General Motors. Producing 505 horsepower and 470 lb-ft of torque, the 7.0L LS7 engine combines big-displacement performance with the lightweight packaging of an aluminum small-block V8.
Built with performance-focused components, the LS7 427 crate engine features a 4.125-inch bore siamesed aluminum block, forged steel crankshaft, lightweight titanium connecting rods, and CNC-ported 356-T6 aluminum cylinder heads with 2.20-inch titanium intake valves.
The high-flow cylinder head design supports strong breathing and responsive high-RPM performance, with the engine capable of operating to a 7,000 RPM redline.
For builders looking for a 7.0L LS7 crate engine with factory-developed performance credentials, the LS7 provides an exceptional foundation for muscle cars, restomods, road-race builds, and other high-performance applications.
