Product Information

HOLLEY INTAKE MANIFOLD

The new single plane intake manifold is designed to provide a broad RPM powerband for high-performance street/strip engine applications to a maximum engine speed of 7500 RPM. The carburetor-mounting pad is designed to accept all stock or aftermarket square-bore carburetors with manual or electric chokes. These intake manifolds are designed to accept most stock hardware and accessory brackets, but offer performance features, like an updated plenum divider area, a 1" shorter height than the 300-25 manifold, and a choice of two distributor clamp locations. The isolated design of the air/fuel passages helps to increase charge air density and performance.

  • Single Plane with Isolated Plenum
  • Square Bore Carburetor Mounting Flange
  • Isolated Water cross-over
  • Power band: 2500-7500 RPM
  • Height: Front 4.18", Rear 5.28"
  • Port Size: 1.92" height 1.20" width
  • Built to last

Holley built their excellent reputation on over 100 years of experience, which is why they're one of the leaders in fuel delivery systems and the choice of every NASCAR team for the past four decades.
