SBC Street Stock Header 602 Crate 1-5/8in

The SBC Street Stock Header 602 Crate 1-5/8in from Schoenfeld is purpose-built for small-block Chevy street and bracket racing applications, delivering optimized exhaust scavenging for crate engines rated at 602 cubic inches. This header directly addresses the needs of budget-conscious racers and street performance enthusiasts who demand reliable, dyno-proven flow characteristics without the premium price tag of full custom fabrication. Whether you're building a turnkey crate motor platform or upgrading an existing street stock setup, this header bridges the gap between entry-level performance and serious competition-grade engineering.

The 1-5/8-inch primary tube diameter is engineered to match the cylinder head port velocity and exhaust gas flow characteristics of the 602 crate platform, preventing backpressure buildup that would otherwise rob peak horsepower and mid-range torque. Schoenfeld's tuned collector design promotes smooth gas merging and reduces turbulent reversion, critical factors for consistent performance across variable RPM ranges encountered in street driving and bracket racing. The header's construction utilizes mandrel-bent tubing and precision-welded joints to ensure durability under repeated thermal cycles, while the compact footprint accommodates tight engine bay installations common in street stock competition vehicles.

This header excels for small-block Chevy street stock racers, bracket racing competitors, and street performance builders seeking bolt-on efficiency gains without extensive engine bay modifications. The 1-5/8-inch tube sizing pairs seamlessly with factory or aftermarket exhaust systems tuned for similar displacement ranges, making it an ideal foundation for complete exhaust system planning. Installation requires standard header mounting hardware and basic mechanical knowledge; proper gasket sealing and torque sequencing ensure longevity and leak-free operation. Weighing 26.13 lbs, it represents a manageable balance between structural integrity and lightweight design suitable for weight-conscious competition platforms.
