Offenhauser 5407 Ford FE Dual Quad Manifold

Description

Ford 332-352-360-390-406-427-428  Dual Quad manifold for Competition.  

Carb Information – We recommend AFB carbs for all Dual Quad manifolds to preclude possible carb clearance problems.  When using Holley carbs, it may be necessary to mount them sideways or move them forward and rear.  See adapters #5832 and #5880 on page 38 of the catalog.  These carb adapters do not solve the clearance problem in every case.  BE SURE AND CHECK.   

For Holley use #5880
