After only a few short years, the LS 7.0L engine of the Corvette Z06 is a legend in its own time. Sure, it's got more than 500 naturally aspirated horsepower and 470 lb-ft of torque, but the exceptional high-rpm performance and low-end grunt gives this 427-cubic-inch combination the great tractability for which LS engines are known and the pulling power expected of a Big-Block with its historic displacement.
The LS7 features a unique big-bore cylinder block that is anchored with a forged crankshaft, featherweight titanium connecting rods and durable, coated-skirt pistons. But it's the airflow capability of the LS7's cavernous, CNC-ported heads that enables its tremendous power. Large-volume, straight-passage intake runners channel air directly through 2.200-inch titanium intake valves. The mixture is burned in large, 70cc combustion chambers and what's left exits through 1.610-inch sodium-filled exhaust valves. And did we forget to mention the dry sump oiling system? This is a serious engine for serious enthusiasts.
GM Performance Parts' LS7 7.0L crate engine package includes a production-style engine with the dry sump oil pan. You'll need to supply the external oil supply and oil lines to the engine, but the rest of the assembly is fully dressed, including the manifold assembly with injectors and electronically controlled throttle body, and log-style exhaust manifolds.
