SBF Header 1-5/8

The SCHOENFELD SBF Header 1-5/8 (Part Number 3522) is a purpose-built exhaust manifold system designed specifically for small block Ford engines in high-performance and demolition derby applications. This header set features 1.625-inch primary tubes and is engineered to route exhaust through the hood, a critical requirement in demolition derby competition where hood clearance and impact protection take priority over conventional underhood routing. The pair includes all necessary gaskets and hardware for a complete bolt-on installation.

Constructed from steel and finished in durable black paint, the 1-5/8-inch primary diameter is sized to balance scavenging efficiency with the compact packaging constraints typical of modified small block Ford builds. This tube diameter works well in the mid-range RPM band where most street and competition small blocks operate, providing solid exhaust gas velocity without excessive backpressure. The hood-exit design accommodates modified hood panels or openings, a practical necessity in demolition derby vehicles where engine visibility and cooling take precedence. Weighing 26.5 pounds per pair, these headers add minimal weight while delivering the structural integrity required for impact sports and high-RPM service.

SCHOENFELD headers are purpose-engineered for demolition derby competitors and small block Ford enthusiasts building vehicles for competition or extreme duty. The hood-exit configuration is particularly valuable in demolition derby where conventional side or rear exhaust routing is impractical or prohibited by event rules. The included gaskets and fasteners eliminate sourcing secondary components, streamlining the installation process for drivers preparing vehicles for the derby arena or high-performance track use.

Small block Ford headers with hood exhaust exits represent a specialized category driven primarily by demolition derby competition and unconventional builds. Standard performance headers prioritize underhood routing and appear frequently in street rods and track cars; SCHOENFELD's approach prioritizes compliance with demolition derby regulations and practical installation where hood-top exhaust venting is the design requirement. This header is not intended for vehicles requiring conventional exhaust routing or street-legal emissions compliance.
