After only a few short years, the LS7 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-in 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,
friction-coated 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 2.20-inch
titanium intake valves. The mixture is burned in large, 70cc combustion
chambers and what’s left exits through 1.61-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 productionstyle
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.
