Holley 300-900 Details
Holley's low-profile intake manifold for Ford's 7.3L "Godzilla" engine, when paired with a 20-340/20-340BK oil pan and accessory drive kit, allows for easy installation into vintage vehicles, kit cars, and other space-restricted applications while retaining the factory hood. The design focus for this manifold was equal cylinder distribution and great street manners. This low-profile intake manifold offers a much cleaner alternative to the original plastic intake, provides anywhere from 2 to 3.5-inches of additional clearance, corrects the OE throttle body angle by 55 degrees, and increases the opening to 92mm. With three throttle body options, sturdy cast aluminum construction, a removable lower panel, and long runners to maintain the 7.3-liter's already substantial torque offering, this is a must-have for any "Godzilla" project.
Heater applications - Use 300-901 heater line adapter. This adapter will work with either the original Ford or Holley intakes and is required for A/C applications and the Holley low intake.
