This EFI 351W Hi-Ram manifold comes with a 105MM 1986-95 Ford 5.0 throttle body flange side mount top. The runner length and tapered cross section design will perform well for a wide range of engine combinations. The engineering team also redesigned the water crossover passage to allow room for distributor phasing. Aggressive, bold, race-bred styling will make bad intentions clear for drag race, muscle car, marine, off-road, sandrails, pulling trucks, track, street-rod applications and more!

HOLLEY EFI,Warning:
HOLLEY EFI,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.
