Edelbrock Low Profile Intake Elbow 90mm Throttle Body to Square-Bore Flange Part Number 3848

This Edelbrock Low Profile elbow was designed for limited hood clearance applications. This adaptor can be used with our 29085 Victor Jr LS1 but cowl trimming and an SS hood are required. The 3848 Elbow can be used in other square bore (4150 style) manifold applications as well. It can be mounted forward, backward, or sideways on any of our Victor EFI Square bore (4150) style manifolds. Because of its low profile a one inch spacer is required for small or Big Block Chevy forward mount configurations to clear the water neck. It can be used with an LS1 80 mm (must use PN 2737 adaptor) or Edelbrock PN 3869 90mm Universal, or Ford style 75mm throttle bodies. The 3848 adaptor features: Bolt pattern fits LS1, LS2 and Ford 5.0l based throttle bodies, adapts to standard (4150 style) square bore manifolds, Fits manifold either in a forwards, backward, or sideways configuration, The throttle bore center sits 7.00" forward and only 2.00" up from the manifold 4150 flange, The throttle body points downward on a 5 Deg angle. For ultra-low applications out PN 3847 elbow sits 9.00" forward and only .56" above the flange, with a 12 Deg downward throttle body angle.

• As-Cast Finish

The Edelbrock Low Profile Intake Elbow (Part Number 3848) is designed for high-performance applications requiring limited hood clearance. This versatile adapter enables seamless connection between 75mm, 80mm, or 90mm throttle bodies and standard 4150-style square bore manifolds, making it suitable for a wide range of engine setups. Its low-profile design helps maintain hood clearance, especially useful in tight engine compartments or custom builds. The elbow can be mounted in multiple orientations—forward, backward, or sideways—on Edelbrock's Victor EFI square bore manifolds, providing flexible installation options for different engine configurations. For optimal fitment with small or Big Block Chevy engines in forward mount setups, a 1-inch spacer is recommended to clear the water neck, ensuring proper clearance and functionality.
The adapter features a bolt pattern compatible with LS1, LS2, and Ford 5.0L throttle bodies, including 75mm, 80mm, and 90mm sizes. It is designed with a throttle bore center located 7 inches forward and 2 inches up from the manifold flange, with a downward-pointing throttle body at a 5-degree angle. For ultra-low applications, Edelbrock offers PN 3847 elbow, which positions the throttle body 9 inches forward and only 0.56 inches above the flange, with a 12-degree downward angle for maximum clearance. The cast finish provides durability and a clean appearance, suitable for both street and racing environments.
This universal EFI elbow is ideal for custom builds, performance upgrades, and engine swaps where space constraints are critical. It is not carburetor-approved, and proper acknowledgment of its EFI-specific design is required during installation. The part is lightweight and easy to install, making it an excellent choice for enthusiasts seeking a reliable, low-profile solution for their EFI throttle body connections.
