SBC Modified Header Long Tube 1-5/8in

The SBC Modified Header Long Tube 1-5/8in by SCHOENFELD is a high-performance exhaust manifold upgrade designed specifically for small-block Chevrolet engines. This product is ideal for engine builders and street/strip enthusiasts who are looking to enhance their vehicle's performance by improving exhaust flow and scavenging efficiency.

Engineered with a long-tube design, this header features a 1-5/8-inch primary tube diameter that optimizes exhaust flow and reduces backpressure. The construction utilizes mandrel-bent tubing to minimize turbulence, ensuring that spent combustion gases are efficiently evacuated from the cylinder head. This design is particularly beneficial for high-lift cam profiles and aggressive timing curves, as it maintains pulse separation and prevents cross-cylinder interference.

This SBC Modified Header is compatible with both carbureted and fuel-injected small-block Chevrolet engines, making it a versatile choice for street machines and racing applications. Its modified design allows for installation in tight engine bays where traditional long tubes may require excessive modifications. With this header, enthusiasts can expect significant improvements in horsepower and overall engine performance.
