SBC Stock Car Header 1-3/4in x 3in

The SCHOENFELD SBC Stock Car Header 1-3/4in x 3in (model 196-3) is a purpose-built exhaust manifold system designed for Small Block Chevy engines competing in IMCA and UMP stock car racing. This pair delivers optimized primary tube diameter and collector size to maximize scavenging efficiency across the RPM range typical of stock car competition, where consistent power delivery and reliable performance are non-negotiable.

The 1-3/4 inch primary tubes and 3 inch collector diameter are engineered for Small Block Chevy applications where displacement and cam profile fall within sanctioned stock car classes. Steel construction with black paint finish provides durability under the sustained heat cycling of competition. The system ships complete with gaskets and mounting hardware, eliminating the need for sourcing separate components. At 25.55 lbs per pair, these headers are lightweight relative to cast iron alternatives while maintaining the structural integrity required for long-term track duty.

Stock car competitors running IMCA or UMP regulations will recognize SCHOENFELD as an established manufacturer in circle track racing. These headers address the specific needs of drivers who must balance power gains with rule compliance—tube sizing and configuration conform to typical stock car specifications while delivering measurable improvement over original cast manifolds. Installation is straightforward for anyone familiar with SBC header fitment, and the included gaskets ensure proper sealing right out of the box.

For serious stock car racers building or refreshing a Small Block Chevy package, exhaust scavenging is a critical factor in overall engine efficiency. These SCHOENFELD headers deliver proven performance in the racing environment they were designed for, backed by the trust of competitors who depend on reliable power week after week.
