Corvette Z06  With 505 horsepower  and 475 pounds  of torque
The all-new LS7 of the ’06 Z06 reintroduces the 427-cubic-inch engine to the Corvette lineup. Unlike the previous 427 engine, which was a big-block design, the new 7.0-liter LS7 is a small-block V-8 - the largest-displacement small-block ever produced by GM and a tribute to its 50 years as a performance icon.
With 505 horsepower and 475 lb.-ft. of torque, it also is the most powerful passenger car engine ever produced by Chevrolet and GM. The LS7 is easily identified under the hood by red engine covers with black lettering.


The LS7 shares the same basic Gen IV V-8 architecture as the Corvette’s 6.0-liter LS2, but the LS7 uses a different cylinder block casting with pressed-in steel cylinder liners to accommodate the engine’s wide, 104.8-mm-wide cylinder bores; the LS2 has 101.6-mm bores. And when compared to the LS2, the LS7 also has a different front cover, oil pan, exhaust manifolds and cylinder heads.
Internally, the LS7’s reciprocating components make use of racing-derived lightweight technology, including titanium connecting rods and intake valves, to help boost horsepower and rpm capability. The rpm fuel shut-off limit is 7000 rpm.
