Most Powerful Small-Block Ever - Available in a Crate
DETROIT - Chevrolet unveiled the 2006 Corvette Z06 at Detroit's North American International Auto Show in January, and now GM Performance Parts is unveiling the crate engine version of the LS7 engine that powers it. This latest Z06, billed as "the fastest, most powerful car ever offered by Chevrolet and GM," has enthusiasts looking for that kind of power in a crate engine. GM Performance Parts is ready to end that search as it offers the LS7 (P/N 17802397) at GM dealerships and Authorized Centers, nationwide in August.
This small-block V-8 dreams big, displacing big-block cubic inches at 7.0 Liters (427 cubic inches) and big-block power at 500 hp at 6200 rpm. It also benches 475 lb.-ft. of torque at 4800 rpm. Helping to create its high power and high revving capability are details such as cylinder heads with computer numerical control (CNC) intake and exhaust ports and combustion chambers - which creates ports with surgical accuracy for maximum power production. In addition, the intake valves and connecting rods are made out of high-strength lightweight titanium.
The LS7 engines are assembled by hand at GM Powertrain's new Performance Build Center in Wixom, Mich.
Pricing will be announced mid-summer; however, early estimates indicate that the GMPP LS7 crate engine will sell for well below the cost of comparable custom-built aftermarket engines.
Enthusiasts who must have the latest technology, maximum horsepower and the largest production cubic-inch displacement small-block ever built will be able to purchase the LS7, as well as other GM Performance Parts crate engines, blocks, heads and components, from GM dealerships or GMPP Authorized Centers nationwide. Following the release of the LS7 in a crate, GMPP will offer select parts, such as the crankshaft, connecting rods, cylinder heads and valves separately, and in kit form.
