SBC Modified Long Tube Header 1-3/4in

The SBC Modified Long Tube Header 1-3/4in by SCHOENFELD is designed for serious small-block Chevrolet builders who are looking to enhance exhaust scavenging and engine efficiency. This long-tube header is a significant upgrade for any SBC platform, whether for street performance or competitive racing, as it optimizes the flow of exhaust gases from the cylinder head to the collector.

Featuring a primary tube diameter of 1-3/4 inches, this header is specifically engineered for modified SBC engines producing between 350 and 450 horsepower. The mandrel-bent construction minimizes turbulence and maintains a consistent tube diameter, which is essential for preventing backpressure spikes that can hinder performance. The swept-back collector design and extended tube length work together to enhance exhaust scavenging, creating a low-pressure zone that helps pull fresh air into the cylinders.

Ideal for both naturally aspirated and forced-induction setups, the SBC Modified Long Tube Header is a proven choice for mechanics and engine builders looking to maximize performance. Its design philosophy has been validated through decades of racing and street applications, ensuring compatibility with various exhaust system tunings.
