The standard engine in the Chevrolet Corvette is the perfect combination of high technology and uncompromising performance. Our LS3 crate engine comes complete; from the Corvette-specific oil pan to the ignition system, it's all here. 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 equipped 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.

In the 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.

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 an ECU/wire harness to get the baddest production LS engine of them all up and running in your project vehicle. It also includes a 9-bolt crankshaft flange that may require an adapter for use with some transmissions.
