Holley 300-273 8.2" SBF Ford Hi-Ram EFI Manifold

8.2" SBF Ford Hi-Ram Intake Manifold with 105mm LS Throttle Body Flange Top.

Part Number: 300-273

The EFI Hi-Ram manifold line has a new addition for the 8.2" SBF Ford application. This manifold comes with a 105MM LS throttle body flange 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! Manifold is designed for a 8.2" deck height. *** A low profile distributor will be needed when using this manifold. We have a Sniper Hyperspark version #565-322 and a Holley EFI Dual Sync #565-211 available. This intake manifold is designed for use with aftermarket cylinder heads. Please see the diagrams in the product images for other dimensions. • Cast aluminum construction. • EFI fuel rails are machined for -8AN O-ring Fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system and come standard with EFI Hi-Ram kits. • Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations

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.
