CHEVY LS3 430hp

The LS3 6.2L is the 430-hp standard engine in the Chevrolet Corvette and is a fantastic combination of high technology and uncompromising performance. Our LS3 crate engine comes complete, from the CHEVY SS oil pan to the ignition system. It also includes the EFI intake manifold assembly with injectors and throttle body, exhaust manifolds, water pump, balancer, 58X reluctor wheel, and 14-inch automatic-transmission flexplate. Inside, the LS3 is filled with components designed for high performance and longevity. The aluminium 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 2.16-inch intake valves and 0.522-inch lift on the 1.59-inch exhaust valves, enhancing the LS3's tremendous airflow and broad torque curve.

CHEVY LS3 480hp

Our engineers never stop tinkering. When they 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 480 horsepower and 475 lb-ft of torque. Thats nearly 12 percent more power and torque from a simple camshaft change! We wasted no time in adding that terrific combination dubbed LS376/480 to our crate engine portfolio. The key to the power boost is the Hot Cams 0.525-inch lift on both the intake and exhaust sides, along with 219-degree/228-degree duration specs. Thats less lift on the intake side than the stock LS3 cam, but considerably more duration, allowing the valves to stay open a little longer to draw in more air from the rectangular-port L92-style heads.

Corvette Z06's LS7

In annals of high-performance engines, the Corvette Z06's LS7 will be remembered as a benchmark in naturally aspirated power. It will also go down as one of the most popular LS crate engines ever offered, with 505 horsepower and 470 lb-ft of torque. Within its classic 427-cu-in displacement, engineers extracted Big-Block grunt from its high-revving Small-Block package. It features a unique, big-bore cylinder block that is anchored with a forged crankshaft, featherweight titanium connecting rods, and friction-coated pistons. But it's the airflow capability of the cavernous, CNC-ported heads that enables its tremendous power. Large-volume, straight-passage intake runners channel air directly through 2.20-inch titanium intake valves. Chevrolet Performance's LS7 7.0L crate engine package includes a production-style engine with the dry sump oil pan. You'll need to supply the external oil supply and oil lines to the engine, but the rest of the assembly is fully dressed, including the manifold assembly with injectors and electronically controlled throttle body, and log-style exhaust manifolds. Use our LS7 controller kit (P/N 19258553) to get it running in your project vehicle.


Chevrolet Performance is thrilled to offer the LS9 6.2L supercharged in a fully dressed crate engine package that includes every one of the Corvette ZR1's 638 horsepower! The LS9 is a technological marvel. High-rpm-validated lightweight reciprocating parts, including titanium intake valves, are used, along with high-flow cylinder heads that draw the charge forced on them by a sixth-generation supercharger. It has a high-helix (twist) design that helps the "blower" deliver greater power at the low end and sustains it longer through the rpm band for broad, on-demand power, whether off-idle or at speed. Chevrolet Performance's LS9 crate engine assembly includes the dry sump oil pan and provisions for the charge cooler's liquid cooling system. You'll need an external oil tank,* external coolant tank* (for the charge cooler), and ECU/wire harness to get the baddest production LS engine of them all up and running in your project vehicle. It also includes a nine-bolt crankshaft flange that may require an adapter for use with some transmissions.

Cadillac LSA

The Cadillac CTS-V's 6.2L supercharged LSA engine delivers 556 horsepower with refinement that is rare in the world of high performance. It is smooth, quiet, and well-balanced all while delivering breathtaking power. A unique aluminium cylinder block casting houses a forged-steel crankshaft and super-tough reciprocating parts, integrated piston-cooling oil jets, and high-flow cylinder heads that support the airflow enabled by a 1.9L, sixth-generation supercharger with four-lobe, high-twist rotors. The advanced rotor design broadens the supercharger's effective range, enhancing low-rpm torque and high-rpm horsepower. Chevrolet Performance's LSA 6.2L supercharged crate engine package comes fully dressed, from the top of the charge-cooled supercharger assembly to the ignition system, water pump, balancer, and more. It is a less-costly alternative to the LS9 engine and makes a great transplant for any off-road LS-powered vehicle or pre-1976 car or truck. It also comes with conventional wet-sump lubrication system. NOTE: This engine includes an eight-bolt crankshaft flange that may require an adapter for use with some transmissions.

LS3 480hp T56 Connect & Cruise

Mixing the capable LS "Hot Cam" with the powerful 6.2L LS3 takes affordable performance to a great, new level - 480 horsepower and 475 lb.-ft. that will wake up your vintage Camaro, Chevelle or "shoebox" Chevy. The 4L70-E four-speed overdrive transmission backs the LS376/480 with strength and durability. Put this combo to work in your classic cruiser and enjoy a great balance of performance and efficiency! Each Connect & Cruise kit delivers a brand-new, fully assembled crate engine, an electronically controlled overdrive transmission, electronic control modules for both and the engine control hardware to get it all running in your project vehicle including the mass airflow sensor, oxygen sensors and even the special throttle pedal for the engines' electronic throttle bodies. Chevrolet Performance engineers matched the engines with their respective transmission, ensuring it was up to the task of channeling big power with absolute dependability. The engine controller is specially calibrated to run the engine without some of the production-vehicle features that aren't required in an older vehicle. That means no "trouble" codes and no need for third-party tuning. Better still, the systems' unique SuperMatic transmission controller is designed to work with the engine controller for a seamless, "plug and play" installation that is quick, easy and intuitive. Detailed instructions outline all the necessary steps.


An engine with 454 cubic inches of displacement will always be associated with higher-performance Chevys, and that tradition continues with the all-new LSX454 crate engine The new LSX six-bolt cylinder heads are based on the racing-derived LS7 heads that help deliver more than 500 horsepower in the Corvette Z06. They enable tremendous low-end torque and great high-rpm power. The LSX454 is delivered in Long block form. It also comes dressed with great-looking, all-new orange powder-coated valve covers with LSX454 logos engraved and painted black.


The ZZ454/440 offers tremendous value in a big-block crate engine. Based on the proven 454 HO with its Gen VI 454 block, the addition of GM Performance Parts Signature series aluminum heads reduce weight and increase horsepower to 440, up from the 454 HOs 425.
