2.400 E/D BBC Intake Valve

The Manley 2.400 E/D BBC Intake Valve (MAN11582-1) is a severe-duty intake valve designed specifically for big block Chevy engines that require exceptional performance in extreme conditions. This single intake valve is ideal for builders and operators who are rebuilding or upgrading their engines for racing, high-performance street use, or commercial heavy-duty applications.

Engineered with a 2.400-inch head diameter and a 0.342-inch valve stem, this valve provides the necessary flow characteristics and structural integrity for high-rpm, high-boost applications. Its stainless steel construction throughout the 6.600-inch length ensures superior corrosion resistance and durability, making it suitable for demanding engine environments. The E/D (Evolution/Duramax) designation signifies its severe-duty classification, perfect for engines operating under sustained high stress.

This intake valve is particularly beneficial for those looking to optimize flow volume while maintaining structural rigidity, essential for engines running elevated boost pressures or nitrous systems. The stainless steel material selection resists thermal cycling degradation and corrosion, extending valve life in challenging conditions. Whether for racing or heavy-duty applications, this valve is a reliable choice for enhancing engine performance.
