Header SBC Modified Hdr Long Tube Crate 1-5/8in

The Header SBC Modified Hdr Long Tube Crate 1-5/8in by Schoenfeld is designed for small-block Chevy engine builders and street performance enthusiasts. This long-tube header is specifically engineered for modified SBC applications, where factory exhaust manifolds may limit power and throttle response. It is suitable for both crate engine platforms and retrofitting existing engines.

This header features a 1-5/8 inch primary tube diameter, balancing scavenging efficiency with backpressure management, which is essential for crate engine calibration. The long-tube design allows for improved exhaust gas velocity and cylinder-to-cylinder isolation compared to stock manifolds. Schoenfeld's manufacturing ensures consistent mandrel bends and precise collector geometry for reliable performance.

Ideal for crate engine installations, street rods, and modified street cars, this header helps alleviate bottlenecks created by factory exhaust paths. It is particularly beneficial for modified SBC engines with displacements typically ranging from 350 to 400+ cubic inches, enhancing mid-range torque while maintaining top-end power. This product is a solid choice for those looking to improve their vehicle's performance.
