Chevy LS3 E-CNC 230 Cyl. Head 69cc Assembled

The Chevy LS3 E-CNC 230 Cyl. Head 69cc Assembled by Edelbrock is a premium cylinder head solution engineered for serious LS-platform enthusiasts looking to maximize airflow and power output. This assembled head eliminates the time and complexity of sourcing individual components, delivering a plug-and-play upgrade path for street machines, race vehicles, and high-performance restorations.

Edelbrock's E-CNC technology employs precision computer numerical control machining to refine every critical flow path, valve seat angle, and chamber geometry. The 69cc combustion chamber volume provides an excellent balance of compression ratio compatibility across stock and modified LS3 platforms, while the 230-port designation refers to the optimized intake and exhaust port flow characteristics that outperform OEM castings.

This assembled configuration includes quality valve components, hardened seats, and precision guides already installed, saving valuable build time without compromising fitment. Whether you're building a crate engine or refreshing an existing LS3 installation, this head addresses the core bottleneck in stock cylinder head designs, delivering measurable horsepower gains at peak torque and RPM ranges.
