Product Details

The Weiand 8122P Street Warrior intake manifold is engineered specifically for Chevrolet big block V8 engines, delivering optimized performance for street applications with power delivery from idle to 5,500 RPM. This low-rise dual plane design provides excellent torque and drivability across the usable RPM range, making it ideal for street performance builds.

Key Features:

  • Peanut oval port configuration with dimensions of 1.570" high x 1.600" wide for optimal flow characteristics
  • 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 to all cylinders
  • Permanent mold 319 aluminum construction provides lightweight strength and excellent heat dissipation
  • Precision CNC machined surfaces ensure superior gasket sealing and consistent port dimensions
  • Modern design optimized for today's higher output big block engines

The dual plane design splits the intake runners to feed opposing cylinders, improving low-end and mid-range torque for superior street performance and throttle response. This manifold is an excellent choice for street machines, street/strip applications, and performance trucks running Chevy big block engines.
