Sprint Car Header 1-5/8 -1-3/4 Crate Engine

The Sprint Car Header 1-5/8 -1-3/4 Crate Engine from Schoenfeld is purpose-built for serious small-block Chevy applications where maximum exhaust scavenging and header longevity matter. Designed specifically for sprint car competition and high-performance street builds, this pair of headers replaces restrictive factory exhaust manifolds with a tuned, high-flow design that unlocks cylinder-head potential and improves throttle response. For mechanics and engine builders working with crate motors, these headers represent a fundamental upgrade that justifies the investment through measurable power gains and reliability.

Each header features stepped primary tubes ranging from 1-5/8 to 1-3/4 inches, a design that optimizes scavenging across the RPM band by allowing low-end cylinder pressure to push residual gases out efficiently before the exhaust valve closes, while larger-diameter sections handle high-RPM flow without choking. The 3-inch collector consolidates exhaust gases into a single outlet, minimizing backpressure while maintaining velocity—critical for sprint car engines that see constant throttle cycling. Fabricated from mandrel-bent steel tubing and finished in durable black paint, these headers ship with all gaskets and hardware included, eliminating guesswork at installation and reducing leak-prone fitment issues that plague generic alternatives.

Sprint car racers, bracket racers, and small-block Chevy street enthusiasts benefit most from this header set, particularly those running crate motors where factory-style exhaust plumbing becomes a bottleneck. Compatibility is straightforward for small-block Chevy applications; verify your engine's exact displacement and induction setup before ordering to ensure collector sizing suits your intended exhaust system. At 35.4 pounds per pair, these headers are substantial enough to handle sustained high-temperature cycling without warping, yet manageable for single-technician installation. Proper gasket sealing at the flange and periodic heat-shield inspection will ensure years of reliability in both competition and street service.
