*** Please see the diagrams in the product images for other dimensions. *** A low profile distributor will be needed when using this manifold. *** Requires the Use of Holley EFI Dual Sync Distributor - 565-111 Warning: Many Ford vehicle models were originally equipped with a heater core flow restrictor located at either the original heater hose fitting in the factory intake or inline in the inlet heater hose which protects the heater core from damage. If you are replacing the hoses between the engine and heater core or changing the factory fitting check to see if your application requires a flow restrictor. Failure to use the proper flow restrictor will likely result in a damaged or leaking heater core.
