Sprint Car Headers 1-3/4 - 1-7/8

The Schoenfeld Sprint Car Headers 1-3/4 - 1-7/8 (part number 1014LV) are purpose-built exhaust manifolds engineered specifically for small block Chevy sprint car applications. This pair of headers features 1.75 to 1.875-inch primary tubing that transitions into a 3.5-inch collector, optimizing exhaust scavenging and flow characteristics critical for high-RPM circle track racing. The black-painted steel construction provides corrosion resistance while withstanding the extreme heat and vibration environment typical of competitive sprint racing.

The stepped primary tube sizing—moving from 1.75 to 1.875 inches—accommodates cylinder-by-cylinder flow variation while maintaining velocity through the collector. This design reduces back-pressure at peak RPM while improving low-end torque characteristics. Gaskets and hardware are included, eliminating the need for additional sourcing and streamlining installation. At 36.7 pounds total weight for the pair, these headers deliver robust construction without excessive bulk. The compact footprint (20.5 x 10 x 41.5 inches) fits within typical sprint car chassis constraints without requiring major body or frame modifications.

Sprint car racers and small block Chevy engine builders rely on Schoenfeld headers for consistent performance gains in competitive circle track environments. The stepped-tube configuration and collector design address the specific thermal and flow demands of sprint racing, where every fraction of horsepower and consistent power delivery translates to lap time improvements. Proper installation with the included gaskets ensures a reliable seal across the full RPM range, from startup through maximum competition load.

Schoenfeld has established credibility in the sprint car market through decades of focused development on headers specifically for this racing discipline. Their stepped-primary designs reflect genuine engineering tailored to small block Chevy characteristics rather than generic tube manifolds adapted from other applications. Buyers upgrading from stock exhaust or replacing worn headers will notice measurable improvements in scavenging efficiency and throttle response under load.
