Product Details

The Weiand 8125 Street Warrior intake manifold is an optimized dual plane design engineered for modern high-output Chevrolet small block V8 engines. This low-rise manifold delivers excellent street-friendly power and torque across the usable RPM range, with an optimal power band from idle to 5,500 RPM.

Key Features:

  • Low-rise dual plane design for broad torque curve and drivability
  • Universal dual pattern carburetor flange accepts both spread bore (Quadrajet) and square bore carburetors
  • Runner geometry optimized using Computational Fluid Dynamics (CFD) software for even fuel and air distribution
  • Sand cast aluminum construction with precision CNC machining for consistent quality
  • Port dimensions: 1.84 inches height x 1.12 inches width
  • Manifold height: 3.50 inches (front) x 4.50 inches (rear)
  • Ideal power range: Idle to 5,500 RPM

This intake manifold combines advanced engineering with proven dual plane architecture to provide outstanding performance value for street-driven small block Chevy applications. The universal carburetor flange and broad RPM range make it an excellent choice for daily drivers, street rods, and weekend cruisers seeking reliable power gains without sacrificing low-end torque or throttle response.
