SBC Street Stock Headers 1-3/4 x 1-7/8

The SBC Street Stock Headers 1-3/4 x 1-7/8 from SCHOENFELD are engineered for small-block Chevrolet street and stock racing applications where exhaust scavenging efficiency directly impacts power delivery and throttle response. Built for the builder who demands reliable, bolt-on performance without sacrificing streetability, these headers combine proven tube geometry with straightforward installation to unlock horsepower gains that street stock competitors and weekend warriors have relied on for decades. Whether you're prepping a weekend racer or upgrading a carbureted street machine, these headers address the fundamental need to move exhaust gases faster and more efficiently than restrictive factory manifolds.

The 1-3/4 inch primary tube diameter and 1-7/8 inch merge collectors represent a balanced design optimized for small-block Chevrolet displacement ranges typically found in 327 to 400 cubic-inch engines, striking the sweet spot between scavenging velocity and flow capacity across the RPM band. SCHOENFELD's header construction uses mandrel-bent tubing that maintains consistent wall thickness through every bend, minimizing turbulence and dead zones where exhaust velocity drops—a critical factor that separates quality headers from poorly designed alternatives. The tubing diameter progression ensures smooth flow transition from the cylinder head ports through the collector, reducing backpressure while maintaining the exhaust pulse scavenging effect that helps draw the next charge into the combustion chamber.

Street stock competitors and bracket racers building traditional small-block combinations will find these headers compatible with most 262 to 400 cubic-inch SBC platforms, though fitment verification with your specific chassis and engine bay configuration is essential before purchase. Installation requires basic mechanical skills and standard hand tools; expect to modify engine bay clearances on some custom chassis or tight underhood layouts, particularly around the driver-side primary tubes. At 30.3 pounds, the complete assembly remains light enough for weight-conscious builds while maintaining structural rigidity under sustained high-RPM operation, making this SCHOENFELD product a proven, cost-effective choice for serious street stock and small-block street racing applications.
