Header SBC Street Stock 1-5/8in Crate

The Header SBC Street Stock 1-5/8in Crate by SCHOENFELD is purpose-built for small-block Chevy crate engine builders and street stock racers seeking maximum scavenging efficiency without excessive complexity. This header system addresses a critical pain point for budget-conscious engine builders: balancing flow characteristics with street-legal simplicity and longevity.

Schoenfeld's header design minimizes turbulence at the collector while maintaining structural rigidity—critical when thermal and vibration cycles stress weaker fabrication. The 1-5/8-inch primary tube diameter is a proven compromise for small-block Chevy applications, offering optimal scavenging velocity across mid-range RPM bands typical of street stock competition and mild crate motors.

Street stock racers, crate engine swappers, and daily-driver enthusiasts building mild small-block Chevy combinations will appreciate the bolt-on simplicity and proven flow characteristics. The crate-ready configuration means tube routing, collector design, and mounting points are pre-engineered for popular SBC crate packages, eliminating fitment guesswork.
