LS7 7.0L Chevy Performance Crate Engine

505 hp @ 6,300 rpm / 470 lb.-ft. @ 4,800 rpm


A Future Classic

The Chevrolet Performance LS7 7.0L has quickly become a benchmark in naturally aspirated power. It powered Chevy's world-beating C6 Corvette Z06, and has become a popular engine for enthusiasts who want its uncompromising performance in their project vehicle. It’s a hot-rodder’s dream at 505 hp with 470 lb.-ft. torque! 

Within its classic 427 CID, this GM crate motor features 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 its tremendous power. Large-volume, straight-passage intake runners channel air directly through 2.20-inch titanium intake valves.

Chevy Performance’s 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 exhaust manifolds. Use our LS7 controller kit P/N 19258553 to get it running in your project vehicle.
