LS7 7.0L V8 Crate Engine
470 lb.-ft. @ 4,800 rpm 505 hp @ 6,300 rpm

A living legend with 427 classic cubic inches! The Corvette Z06’s LS7 will be remembered as a benchmark in naturally aspirated power. It will also go down as one of the most popular LS crate engines ever offered, with 505 horsepower and 470 lb.-ft. of torque, perfect for the track or road and particularly loved by TVR owners looking to replace their engine or kit car builders looking for an engine for their Ultima or Cobra project car.

Within its classic 427-cu-in displacement, engineers extracted Big-Block grunt from its high-revving Small-Block package. It 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. Chevrolet 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 log-style exhaust manifolds. Use our LS7 controller kit - view product here, to get it running in your project vehicle, this comes complete with throttle pedal for the Electronic Throttle Body, wiring harness, O2 sensors and pre-callibrated ECU..
