BBC E-Street Cylinder Head - 290cc 2.19/1.88

The Edelbrock BBC E-Street Cylinder Head with 290cc intake and 2.19/1.88 valve specifications is a high-flow, assembled cylinder head engineered for Big Block Chevy engines seeking reliable performance gains without sacrificing streetability. Built for enthusiasts and performance shops looking to increase horsepower and torque on naturally aspirated platforms, this unit combines proven Edelbrock engineering with affordable, ready-to-bolt performance.

Constructed from aluminum alloy, the BBC E-Street head features a 290cc intake runner volume optimized for mid-range and upper-RPM responsiveness on street and strip applications. The 110cc combustion chamber paired with 1.55-inch dual valve springs ensures reliable operation across the RPM band while maintaining valve control under load. The angle-plug design improves ignition efficiency and flame propagation, translating to cleaner combustion and better fuel economy compared to traditional side-plug configurations.

The BBC E-Street head is ideal for Big Block Chevy 396, 427, and 454 cubic-inch engines in street rods, muscle cars, and light-duty performance trucks where balanced power delivery is essential. With precision-honed valve sizes of 2.190 inches (intake) and 1.880 inches (exhaust), this product eliminates machine shop delays and reduces total project costs, making it a great choice for both experienced builders and first-time upgraders.
