The SBC IMCA Headers 1-3/4 by SCHOENFELD are designed specifically for small-block Chevrolet engines used in IMCA racing series and street performance applications. These headers are essential for maximizing exhaust scavenging and improving horsepower in both carbureted and fuel-injected SBC platforms, catering to weekend racers and serious engine builders alike.
Featuring a 1-3/4 inch primary tube diameter, these headers are optimized for mid-range torque and peak power within the RPM range typical of IMCA-legal engine combinations. The mandrel-bent primary tubes ensure a consistent diameter throughout, minimizing turbulence and allowing for smooth exhaust gas flow without restrictive bends or crimps.
These headers are particularly beneficial for IMCA racers, bracket racing competitors, and street rodders who need to adhere to sanctioned engine build specifications while maximizing power output. Their robust construction is designed to withstand the thermal and mechanical stresses of high-RPM operation, making them a reliable choice for competitive environments.
