    Holley 300-272BK Details

    The EFI Hi-Ram manifold line has a new addition for the 8.2" SBF Ford application. This manifold comes with a 95mm 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.

    • Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations
    • 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
    • Cast aluminum construction

    *** A low profile distributor will be needed when using this manifold. Holley offers a Sniper Hyperspark version #565-322 and a Holley EFI Dual Sync #565-211.

    • 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.
