    Dimensions

    Note:

    • This manifold requires the use of a low profile distributor, 510-565-211 or 510-565-322 (sold separately) 
    • 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

    Features:

    • Made for side-mounted throttle bodies utilizing 1986-1995 Ford 5.0L 95 mm Throttle Body Pattern
    • Lid can be mounted onto an existing 351W and 8.200 in. Hi-Ram manifold base
    • EFI fuel rails are machined for -8 AN O-ring fittings with passages designed to accommodate high-flow fuel as well as dampen pressure pulsations in the fuel system
    • 3/32 in. round O-ring cord plenum top gasket
    • The runner length and tapered cross section design will perform well for a wide range of engine combinations
    • The water crossover passage has been designed to allow room for distributor phasing

    Emissions Note:

    This part is only legal for sale and use on Uncontrolled (Non-Emissions Controlled) Vehicles or on vehicles used solely for the purposes of closed competition racing.
