BBC O/P Intake Manifold 4500 - Track Warrior

The WEIAND BBC O/P Intake Manifold 4500 - Track Warrior is purpose-built for serious big-block Chevrolet engine builders targeting maximum airflow on dedicated track platforms. Designed for competitors and performance enthusiasts who demand race-level induction efficiency, this manifold bridges the gap between street capability and full competition performance. Whether you're running a bracket racing program, road course assault, or drag strip campaign, the Track Warrior configuration prioritizes volumetric efficiency and thermal management critical to sustained high-RPM operation.

This over-and-under design features dual-plane runner geometry optimized for the 4500 RPM powerband, delivering improved low-to-mid-range torque response while maintaining high-RPM breathing capability essential for extended track sessions. The manifold's aluminum casting construction resists thermal distortion under sustained boost or naturally aspirated high-output scenarios, while the Track Warrior specification ensures optimized port matching for BBC cylinder head compatibility.

Track-focused builders and experienced mechanics benefit most from this manifold's application-specific tuning, particularly those running solid-roller cam profiles and aggressive ignition timing curves. Weighing 19.05 lbs and measuring 13 x 6.75 x 25 inches, the manifold integrates seamlessly into tight engine bay configurations without compromising carb pad clearance or fuel system routing on competition vehicles.
