In the annals of high performance engines, Chevrolet Performance LS7 7.0L crate engines will be remembered as a benchmark in naturally aspirated power, with 505 hp and 470 ft.-lbs. of torque. Within their classic 427 cu. in. displacement, engineers extracted big block grunt from their high-revving small block package. They feature a unique, big-bore cylinder block that is anchored with a forged crankshaft, featherweight titanium connecting rods, and friction-coated pistons. But it's the airflow capability of the cavernous, CNC-ported heads that enables this tremendous amount of power. Large-volume, straight-passage intake runners channel air directly through 2.20 in. titanium intake valves. Chevrolet Performance's LS7 7.0L crate engine packages include 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. Chevy Performance recommends their LS7 controller kit to get your new LS7 up and running in your project vehicle.
