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. Street stock competitors and crate engine enthusiasts rely on headers like this to extract reliable power while staying within class restrictions.

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. Schoenfeld's header design minimizes turbulence at the collector while maintaining structural rigidity—critical when thermal and vibration cycles stress weaker fabrication. The crate-ready configuration means tube routing, collector design, and mounting points are pre-engineered for popular SBC crate packages, eliminating fitment guesswork. Weighing 25.3 pounds and measuring 21 x 10 x 33 inches, this header fits tight engine compartments without sacrificing durability or exhaust scavenging area.

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. This header works best in naturally aspirated applications from 5,000 to 6,500 RPM, where primary tube sizing and collector geometry maximize cylinder evacuation. Installation pairs smoothly with standard small-block Chevy engine mounts and transmission tunnel configurations found in popular platform swaps. Verify crate package compatibility before ordering to ensure mounting boss alignment and clearance with your specific application.
