    A Living Legend with 427 Classic Cubic Inches!

    In the history of high-performance engines, 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. Unlike LS1/LS6 engines, the LS7 uses a siamesed bore cylinder block design which is required for its big 4.125" bores. Competition-proven heads and lightweight components, such as titanium rods and intake valves, make the LS7 a street-tuned racing engine!

    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 Corvette 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.

    Does this engine come with the oil pump and i want to put it in a 2003 vy ss commodore and still drive it on the street

    Asked by: Kram86
    No oil pump included, and no electronics included. You will have to determine if this is a viable swap. It will require fabrications and modification to work properly.

    Can I do a engine swap from my 2008 Chevy Impala SS LS4?

    Asked by: Big Roosevelt
    This will not fit into the front wheel drive chassis.
