Holley EFI - Holley 351W Ford Hi-Ram EFI Manifold 300-242

The EFI Hi-Ram manifold line has a new addition for the 351W Ford application. This manifold comes with a 105MM LS throttle body flange top, a 95mm LS throttle body top is also available. 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!

Manifold is designed for a 9.5" deck height.

Manifold width is 11.32".

Tech Resources:

*** This Holley Hi-Ram intake manifold series is designed for Ford 351W engines. This intake manifold is designed for use with aftermarket cylinder heads. OE cylinder heads can also be used, but some modifications may be required. The front and rear height measurements listed in the Specs section are referencing the overall height with the top plate installed. Please see the diagrams in the product images for other dimensions. ***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.
