SBC Stock Car Header 1-5/8in to 1-3/4in x 3in

The SBC Stock Car Header 1-5/8in to 1-3/4in x 3in is engineered specifically for the rigorous demands of IMCA and UMP stock car racing. Available for sale, these headers are designed for Small Block Chevy engines where high-performance exhaust scavenging is critical for maintaining competitive lap times on both dirt and asphalt short tracks. By optimizing exhaust flow and reducing backpressure, this system allows racers to extract maximum horsepower and torque from their engine builds within the strict constraints of sanctioned racing regulations. Professional builders rely on these components to provide the durability needed for heat-soaked racing environments.

Constructed from heavy-duty steel with a protective black paint finish, these headers feature a sophisticated stepped primary design that transitions from 1.625 inches to 1.75 inches. This stepped configuration is a deliberate mechanical choice that enhances the velocity of exhaust gases, providing a significantly broader power band that is essential for exiting corners with authority and maintaining momentum. The system terminates in a high-flow 3-inch collector with a specialized 8-inch length, ensuring efficient pressure management and consistent exhaust pulses across the entire RPM range. The precision-welded construction ensures that the header maintains structural integrity even under the extreme vibrations of competitive racing.

This pair of SBC Stock Car Header 1-5/8in to 1-3/4in x 3in comes complete with all necessary gaskets and mounting hardware to streamline the installation process for mechanics and car builders. Designed for a precise bolt-on fit for Small Block Chevy cylinder heads, they are a reliable choice for racing teams looking to upgrade or replace worn-out exhaust components during a mid-season refresh. Review the technical specifications before you buy to ensure these Schoenfeld headers provide the professional-grade performance required for your specific chassis and engine combination. Their compatibility with standard stock car configurations makes them an industry standard for competitive circle track racing.
