Lo basico que cuenta Wikipedia:
The*LS3*was introduced as the Corvette's new base engine for the 2008 model year. It produces 430*bhp (321*kW; 436*PS) at 5900*rpm and 424*lb·ft (575*N·m) at 4600*rpm without the optional Corvette exhaust and is SAE certified. The block is an updated version of the LS2 casting featuring a larger bore of 4.06*in (103*mm) creating a displacement of 6,162*cc (6.162*L; 376.0*cu*in). It also features higher flowing cylinder heads sourced from the*L92, a more aggressive camshaft with 0.551-inch (14.0*mm) lift, a 10.7:1 compression ratio, a revised valvetrain with 6*mm (0.24*in) offset intake rocker arms, a high-flow intake manifold and 47*lb/hr fuel injectors from the LS7 engine.
The L76/L92/LS3 cylinder heads use 2.165*in (55.0*mm) intake valves, and 1.59*in (40*mm) exhaust valves. Improved manufacturing efficiency makes these heads cheaper than the outgoing LS6 heads, and severely undercuts aftermarket heads. The large valves, however, limit maximum rpm - 6000 in the L76 (with AFM), and 6600 in the LS3 (with hollow stem valves).
In addition to the above, a dual-mode exhaust package with a bypass on acceleration is available. The dual-mode exhaust uses vacuum-actuated outlet valves, which control engine noise during low-load operation, but open for maximum performance during high-load operation. The system is similar to the C6 Z06, but uses a 2.5*in (64*mm) diameter exhaust compared to the Z06's 3*in (76*mm). Power is boosted to 436*hp (325*kW) and 428*lb·ft (580*N·m) with this option.
From April 2008, Australian performance car manufacturer, HSV, adopted the LS3 as its standard V8 throughout the range, replacing the LS2. The LS3 received modifications for its application to HSV E Series models, producing 425*bhp (317*kW). The LS3 engine in the E Series II GTS (released September 2009) was upgraded to produce 436*bhp (325*kW). All HSV MY12.5 excluding the base Maloo and Clubsport variants have been upgraded to produce 436*bhp (325*kW).
