The LS3 was introduced as the Corvette's new base engine for the 2008 model year. It produces 424 bhp (316 kW)@5900rpm and 418 lbft (567 Nm)@4600rpm 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 (103.1 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" lift, 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 mm) intake valves, and 1.59 in (40.4 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 -  6600 in the LS3 (with hollow stem valves).

Throttle Body 
Coolant Bypass Kit:

The factory unit passes coolant through the throttle body, warming the air thus producing less horsepower.  Our coolant by-pass kit eliminates the passing of the coolant through the throttle body, keeping the incoming air cooler and providing additional power.   Your climate control
heater will not be affected.  HP FACTOR -  .5 - 1.5
