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.
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!
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 LS376/480 long block is delivered without the intake manifold, coil packs, water pump, exhaust manifolds or other accessories.
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.
LS long-blocks offer the core capabilities of complete crate engines at a low cost, allowing builders to finish the assembly their way. The LS376/525 long block is delivered without the intake manifold, coil packs, water pump, exhaust manifolds or other accessories.
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.
Based on the production Camaro ZL1 engine, the supercharged LSA E-ROD crate engine kit delivers 556 horsepower. The kit includes converters and an evap canister, as well as the engine controller and harness. Pair with the SuperMatic™ 4L75-E transmission for a great, street-legal combination
A new, high-lift camshaft developed for this engine helps produce a GM-estimated 570 horsepower and 540 lb.-ft. of torque, while the new wet sump oiling system eliminates the need for the installer to incorporate a separate oil tank, oil lines and other ancillary components to support the production LS7’s dry sump system.
