6.2L Engine

6.2L Engine

In 2005, the Generation III was superseded by the Generation IV. This category of engines has provisions for high-displacement ranges up to 7,011 cc (7.011 L; 427.8 cu in) and power output to 638 bhp (476 kW). Based on the Generation III design, Generation IV was designed with displacement on demand in mind, a technology that allows every other cylinder in the firing order to be deactivated. It can also accommodate variable valve timing.

A 3-valve per cylinder design was originally slated for the LS7, which would have been a first for a GM pushrod engine; but the idea was shelved owing to design complexities and when the same two-valve configuration as the other Generation III and IV engines proved to be sufficient to meet the goals for the LS7.

This family of blocks were the first of the generation IV small block with the LS2 being the progenitor of this family and generation. This family of blocks has seen a wide range of applications from performance vehicles to truck usage.

Brand new! Fuel-Injected ferocity for performance cars of all ages! 

What do you get when you take Chevrolet Performance’s aggressive ASA camshaft – developed for the high-rpm world of circle-track racing and slip it into an LS3 6.2L engine? The answer is 525 horsepower in one of our most powerful production-based crate engines. We call it the LS376/525 and if take-no-prisoner performance is what you’re looking for in your project, this is it!
The ASA camshaft is a hydraulic roller with .525-inch lift on both sides, along with 226 degrees duration on the intake side and 236 degrees on the exhaust side. Coupled with a tight, 110-degree lobe separation angle, it helps the engine deliver excellent throttle response and breathe exceptionally well at high rpm. And for durability, we complement the cam with higher-rate valve springs.

LS3 & Hot Cam = Loads of Fun!

The hot new small-block V-8 in the GM lineup is the hyper-aggressive LS3. It offers a high-revving 376-cid combination that represents generations of small-block V-8 development and engineering. Not only is the LS3 an amazing engine in its stock configuration, but with those high-flowing rectangular port cylinder heads, the LS3 is loaded with potential. To tap into this, the engineers at GM Performance Parts offer you the LS376/480—an LS3 with an upgraded camshaft that ups power by a whopping 50 horsepower!

The LS376/480 comes with the same great features as the LS3 crate engine. The bottom end includes a 6-bolt aluminum block, nodular crank, high performance rods, and 10.7:1 pistons. The heads are high-flowing rectangular-port L92 units that have been upgraded with high-revving, hollow-stem valves. The same EFI intake manifold feeds the hungry engine, while 1.7:1 roller rockers work with the upgraded camshaft.

  • As one of the newest members of the LS engine family, the LS3 6.2L engine has benefited from all of the forward-thinking technology that has kept this engine series at the forefront of modern performance. It was introduced on the 2007 Corvette and debuts in 2009 in the all-new Camaro. The GM Performance Parts LS3 6.2L crate engine is based on the Corvette application, including the oil pan. It comes complete with the ignition system, manifold assembly with injectors and throttle body, exhaust manifolds, water pump, balancer and 14-inch automatic-transmission flexplate.

Inside, the LS3 is filled with components designed for high performance and longevity. The aluminum block is filled with a sturdy reciprocating assembly that combines with L92-type rectangular-port heads to deliver a 10.7:1 compression ratio. A high-lift, hydraulic roller camshaft delivers a whopping 0.551-inch of lift on the 2.165-inch intake valves and 0.522-inch lift on the 1.59-inch exhaust valves. It holds those valves open for 204-degrees of rotation (intake) and 211-degrees (exhaust), respectively, enhancing the LS3’s tremendous airflow and table-flat torque curve.
