Intake Manifold, 2x4 BBL, 427 Medium Riser

This 390-428 intake is the same one that would have come on any 427 Medium Riser powered vehicle, as well as 1967 Shelby GT500’s.  It has Holley carburetor bolt patterns and improved port designs to deliver significant power increases over the original stock unit.  This is a direct replacement without worrying about old castings that have cracked, been overworked, or repaired.  Also available as a complete unit with carburetors, linkage, fuel log and air cleaner.
