Description
Gen III Hemi EFI Manifold Base - As Cast Finish - Fits 2009-up 5.7L, 2005-2010 6.1L, and 2011-up 6.4L
Part Number: 300-653
The EFI fuel rails are machined for -8AN O-ring fittings with passages large enough to accommodate high fuel flow and dampen pressure pulsations in the fuel system and come standard with EFI Hi-Ram kits.
The Holley Hi-Ram intake manifold is for high-performance applications where induction system height is not limited. Using this Hi-Ram intake with high flowing Gen III Hemi cylinder heads has outstanding potential for naturally aspirated & forced induction applications. Aggressive, bold, race-bred styling will make bad intentions clear for drag race, muscle car, marine, off-road, sandrails, pulling trucks, track, street-rod applications and more!
Intended for use on naturally aspirated, forced induction, or nitrous engines in the 5.7 to 7.2+ liter range, max power at 7500-8500 RPM.
Add even more power to your Gen III Hemi engine with a Holley Hi-Ram intake manifold. This cast intake manifold has large intake ports - fits 2009-up 5.7L, 2005-2010 6.1L & 2011-up 6.4L engines.
The base is designed to be modular in configuration to accept a wide range of EFI tops and to be attractive to builders and fabricators as the foundation for custom induction systems. Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations.
Features and Benefits
• Fits Gen III Hemi Engines w/ Large Intake Ports (1.70” Height x 1.88” Wide) – fits 2009-up 5.7L, 2005-2010 6.1L, 2011-up 6.4L)
• Add Even More Power to the Gen III Hemi Engine with a Holley Hi-Ram Intake Manifold
• Port for OE Style Manifold Absolute Pressure (MAP) Sensor (1 or 2 Bar)
• Overall Height: 11.59”
• Includes EFI Fuel Rails w/ -8 AN O-Ring Fittings & Large Passages to Accommodate High Fuel Flow and Dampen Pressure Pulsations in the Fuel System
• Manifold Base – Available Separately for Custom Induction Systems
• O-Ring Seal to Head – Large Retained O-rings Offer Superior Original Equipment (OE) Style Sealing & Are Easy to Replace
• Runner Length and the Tapered Cross Section Designed to Perform Well for a Wide Range of Engine Configurations
• Billet Oil Fill Cap – Attractive Low Profile Design
• Cast Aluminum Construction w/ Natural Satin or Black Finish
• Works with Gen III Hemi Injectors & Bosch EV-1 Style Injectors
• Cast-In Pads for Adding Nitrous Nozzles
• Positive Crankcase Ventilation (PVC) Ports w/ Adapter Fittings
Early 2003-2008 5.7L Engines Can Use 300-652 adapters to Match the Smaller Intake Ports on these Engines.
The lid on this intake manifold is machined to fit an LS style throttle body since this allows the use a cable operated throttle body (at a reasonable cost).
The 80mm Gen III Hemi Throttle Body (drive by wire) Can Be Used on This Intake - Use w/ 300-660 Adapter Plate.
The 92mm Hellcat Gen III Hemi Throttle Body (drive by wire) Can Be Used on This Intake - Use w/ 300-661 Adapter Plate.
