Sprint Car Headers 1-5/8 to 1-3/4in

The Schoenfeld Sprint Car Headers 1-5/8 to 1-3/4in (model 1022LV-3) are purpose-built exhaust manifolds engineered for high-output small block Chevy engines in competition and performance applications. These headers represent the gold standard for sprint car builds, where every fraction of a second and horsepower gain matters on the track. Designed specifically for drivers and engine builders who demand maximum scavenging efficiency and responsive power delivery, the 1022LV-3 delivers the thermal management and flow optimization that separates winning engines from the rest of the field.

Constructed from high-temperature steel with durable black paint, these headers feature a 1-5/8 to 1-3/4 inch stepped primary tube design that reduces backpressure while maintaining optimal scavenging across the engine's entire RPM range. The 3-inch collector consolidates exhaust flow into a common outlet, allowing for tuned pipe lengths that enhance low-end torque and mid-range power without sacrificing top-end performance. The stepped primary configuration is critical for sprint cars, where variable track conditions demand responsive throttle response and consistent power across wide operating ranges. Gaskets and mounting hardware are included, simplifying installation on small block Chevy platforms from 283 to 400 cubic inches.

Sprint car competitors, engine builders, and performance enthusiasts running carbureted or fuel-injected small block Chevys will find these headers essential for maximizing horsepower and maintaining consistent exhaust scavenging throughout race season. The paired configuration (sold as a set) ensures equal flow characteristics on both cylinder banks, eliminating power imbalances that compromise handling and acceleration. Installation requires basic header knowledge and is best performed by experienced mechanics familiar with small block Chevy engine compartments. Weighing 34.3 lbs and measuring 20.5 x 10 x 33 inches, these headers are engineered for tight engine bay fitment typical of sprint car chassis while delivering professional-grade performance.
