  • Hit the Street FAST with Holley's Dual Plane Intake Manifold

    A dual plane design makes this manifold perfect for low-end torque while still reaching up to 6500 RPM. The cast aluminum construction is light and efficient with consistent wall thicknesses and improved casting quality. O-ring cylinder head mounting flange gaskets provide an OE-style seal that makes installation a snap! Minimum carb flange height means the manifold clears the hood with little to no modification.

    Features
  • Great for carbureted or throttle body EFI street applications
  • 1500-6500 RPM range
  • 4150 square bore carb flange
  • O-ring mounting flange gasket
  • Optimized runner layout and constant cross-sectional area create broad torque curve
  • Front Height: 5.07" (from front lifter valley cover to carb mounting flange)
  • Rear Height: 6.14" (from rear lifter valley cover to carb mounting flange)
