A FUTURE CLASSIC

With its classic 427-cubic-inch displacement and racing-derived features, including featherweight titanium connecting rods, the 505-hp LS7 7.0L made its mark in the C6 Corvette Z06 and advanced its legacy in the fifth-generation Camaro Z/28.

Chevrolet Performance’s powerful LS7 crate engine is based on the production specifications of the Gen 5 Z/28 application, including unique Tri-Y exhaust manifolds, which are designed to take advantage of the engine’s firing order to deliver a combination of pulse separation of adjacent firing cylinders and improved scavenging – all for optimal performance.

The LS7 is hand-assembled at the Performance Build Center at GM’s Bowling Green, Ky., assembly plant. It uses a unique cylinder block casting with pressed-in steel cylinder liners to accommodate the engine’s large, 4.125-inch cylinder bores – with deck-plate boring and honing for optimized bore geometry. The bottom end is complemented by high-flow, CNC-ported heads featuring large-volume, straight-passage intake runners and 2.20-inch titanium intake valves.

Our crate engine package includes a dry-sump oil pan. Builders will need to supply the external oil tank and oil lines to the engine, but the rest of the assembly is fully dressed.
