Product Details

The Weiand 8121 Street Warrior intake manifold is engineered for Chevrolet small block V8 engines, delivering exceptional performance for street-driven vehicles. This dual-plane intake manifold features premium sand-mold casting with precision CNC machining for superior quality and consistent port dimensions.

Key Features:

  • Dual-plane design optimized for street performance with power band from idle to 5,500 RPM
  • Precision CNC-machined mounting surfaces ensure proper sealing and bolt alignment
  • Premium sand-cast aluminum construction for strength and heat dissipation
  • Port dimensions: 2.00" height x 1.06" width for excellent airflow characteristics
  • Manifold height: 3.375" front, 4.50" rear for proper hood clearance
  • Accepts standard Holley/Edelbrock square-bore carburetors

The Street Warrior design provides strong low-end and mid-range torque while maintaining excellent top-end power, making it ideal for daily drivers, street rods, and mild performance applications. The dual-plane configuration improves throttle response and fuel distribution compared to single-plane designs, resulting in better drivability for street use.
