Specifications
The LS7 engine is one of the most iconic and high-performance small-block V8s ever produced by General Motors. Known for its massive displacement, race-inspired engineering, and exceptional durability, the LS7 remains a top choice for restorations, restomods, high-power street builds, and track cars. Our OEM-tested LS7 units are assembled to exacting standards, delivering the raw power, torque, and reliability enthusiasts expect from a flagship Corvette Z06 engine.
The LS7 is a naturally aspirated 7.0L V8 featuring a lightweight aluminum block, forged internals, and high-flow cylinder heads derived from Corvette Racing technology. Its large displacement and efficient breathing give it instant throttle response, a broad torque curve, and outstanding power without forced induction. The LS7’s dry-sump lubrication system, titanium connecting rods, and aggressive cam profile allow it to withstand high RPM and track abuse, making it a favorite for endurance racing, performance swaps, and custom builds seeking big power with OEM reliability.
Engine Variant
C6 Corvette Z06
The standard C6 Z06 came equipped with the 7.0-liter LS7 producing 505 hp and 470 lb-ft of torque. Paired exclusively with a 6-speed manual transmission, it delivers blistering performance 0–60 mph in about 3.7 seconds with a curb weight around 3,150 lbs. The Z06 became legendary for its combination of raw V8 power, lightweight construction, and track-ready handling.
LS7 Crate Engine
The Chevrolet Performance LS7 crate engine is a large 7.0-liter (427-cid) V8 that makes 505 horsepower and 470 lb-ft of torque. It’s built to rev safely up to about 7,000 rpm and uses strong, lightweight parts like a forged steel crankshaft, titanium connecting rods, and CNC-ported heads with titanium valves. Its high 11:1 compression and big 4.125″ x 4.000″ cylinders help it make lots of power, while the dry-sump oiling system keeps the engine well-lubricated during hard driving. Overall, it’s a powerful, race-ready engine designed for high performance and reliability.
