These new elbows were developed by the Edelbrock engineering team using the latest in Computational Fluid Dynamic software. Edelbrock Throttle Body Elbows are the best way to adapt LS1, LS2 and Ford 5.0L-based throttle bodies to EFI manifolds with traditional square-bore mounting pads. An internal divider optimizes flow quantity and distribution into the manifold and they can be mounted forward, backward or sideways on Victor EFI square-bore manifolds. Three version allow EFI tuners to position the throttle body low for hood clearance or higher for max airflow.

These box style elbows add the great EFI appearance to carburetor-style EFI manifolds. Their performance matches the High Flow Elbow 350-3849 up to 400 horsepower. Sideways Mount Box Style elbow 350-3851 is intended for sideways mounted applications. Both accept LS1, LS2 or Ford 5.0L-based throttle bodies.
