Versatile, adaptable and offering almost unlimited potential from Chevrolet Performance’s crate engines and performance parts, the LS engine family is a new standard for high-performance engine installations. Chevrolet Performance has the controller, with engine-specific calibration, and harness kit to help the installation go smoothly and get running quicker, without additional tuning.
The LS3 is filled with components designed for high performance and longevity, starting with a sturdy reciprocating assembly that’s matched with L92-type rectangular-port heads and a high-lift, hydraulic roller camshaft. It all optimizes the LS3’s tremendous airflow and supports a broad torque curve.
LS long-blocks from Chevrolet Performance offer the core capabilities of complete crate engines at a low cost, allowing builders to finish the assembly their way. The LS3 long block is delivered without the intake manifold, coil packs, water pump, exhaust manifolds or other accessories.

With a strong 430HP, the LS3 E-rod crate engine system has a CARB executive order enabling emissions legal performance. The kit includes converters, an evap canister, as well as the engine controller and harness. Pair with the SuperMatic 4L65-E transmission for an excellent street-legal combination.
Chevrolet Performance engineers have developed the LS364/450 as a value-driven foundation for builders and enthusiasts looking to give their earlier LS powered vehicles a high performance shot in the arm.
When our engineers took a production LS3 6.2L (376 cubic inches) engine and swapped the stock camshaft for the racing-inspired LS Hot Cam (P/N 88958753), the result was a stunning 495 horsepower and 473 lb.-ft. of torque. That’s nearly 14 percent more power and torque from just a camshaft change!
Big LS power designed for carburetors. With the proven LS3 engine as its foundation, the LS376/515 crate engine matches the racing-derived ASA Hot Cam and a carbureted induction system to produce 533 horsepower at a stellar 6,600 rpm and 477 lb.-ft. of torque at 5,200 rpm.
Chevrolet Performance’s LS376/525 is our most powerful naturally aspirated 6.2L crate engine. It’s based on the LS3, but adds our aggressive ASA camshaft to expand the performance range, particularly at high rpm, resulting in 525 horsepower and 486 lb.-ft. of torque.
