    Retro Manifold Styling for Your GM LS Engine!
    Holley LS 2x4 Dual Plane Intake Manifolds have the looks and performance of the muscle car era but offer the technology and reliability of modern LS-Series engines. The LS engine does not have an intake-mounted distributor or water neck clearing the way for straight runner paths to the cylinder heads from a choice of dual carburetors or EFI throttle bodies. The nostalgic appearance reflects the tradition of the 1960's Holley Dual 4160 Induction Systems that competed in the streets, drag races, Trans Am Race Series, and Le Mans.

    Features:
  • Cast Aluminum Construction
  • Powerband: 1500 to 7000 RPM
  • Carb Flange Center-to-Center: 8-5/8''
  • Perfect for Street/Performance, Muscle Car, or Street Rod
  • Mount dual 4160-style carburetors or dual 1000cfm EFI throttle bodies
  • Dual plane design for equal distribution and great midrange torque without compromising top-end power

  • Does Holley 300-120 fit your vehicle?
