Holley SBF Hi-Ram EFI Intake Manifolds
Holley introduces a new addition to their manifold line up—the SBF Hi-Ram EFI intake manifolds that come with an LS throttle body flange top (in either 95mm or 105mm throttle body sizes). Their runner length and tapered cross-section design will perform well for a wide range of engine configurations. The Holley engineering team also redesigned the water crossover passage to allow room for distributor phasing. With the aggressive, bold, race-bred styling, there's no doubt that these Hi-Ram EFI manifolds will make your bad intentions clear for drag racing, muscle car, marine, off-road, sandrails, pulling trucks, competition track, street rod applications, and more!
Additional features and specs include:
* Cast aluminum construction
* Available in natural cast aluminum or black powdercoat finish
* Manifold is designed for an 8.2 in. SBF deck height
* EFI fuel rails are machined for -8 AN O-ring fittings, with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system; they come standard with EFI Hi-Ram kits
* Plenum top gasket type: 3/32 in. round O-ring cord
* A low-profile distributor will be needed when using this manifold (sold separately)
