SBC Header 1-5/8

The SBC Header 1-5/8 by SCHOENFELD is a precision-engineered exhaust manifold designed specifically for small-block Chevrolet performance applications. This product is ideal for automotive enthusiasts and serious engine builders looking to enhance their vehicle's performance. By improving exhaust scavenging and reducing backpressure, this header helps unlock the engine's potential.

Featuring a 1-5/8-inch tube diameter, the SBC Header strikes an optimal balance between scavenging efficiency and installation practicality. The mandrel-bent primary tubes maintain a consistent internal diameter throughout each runner, which minimizes turbulence and flat spots often found in welded designs. This design ensures smooth exhaust gas evacuation across the entire RPM band, particularly during critical transition zones.

This header is particularly beneficial for street-driven SBC engines, including 305, 327, 350, and 383 displacements. The 1-5/8-inch tube sizing avoids velocity loss associated with larger piping while maximizing scavenging in standard displacement applications. Fitment is straightforward for most traditional small-block Chevrolet setups, making it a versatile choice for various builds.
