A legend in its own time. The LS7 is the standard engine in the Corvette Z06 and its 7.0L displacement (427 cubic inches) makes it the largest small block engine offered in a production car. Unlike LS1/LS6 engines, the LS7 uses a siamesebore cylinder block design - required for its big, 4.125-inch bores. Competition proven heads and lightweight components, such as titanium rods and intake valves, make the LS7 a street-tuned racing engine, with 505 horsepower. LS7 engines are built by hand at the GM Performance Build Center in Wixom, Mich.
Horsepower: 505
