Holley 300-274 8.2 Inch SBF Hi-Ram EFI Manifold Base

The EFI Hi-Ram manifold line has a new addition for the 8.2" SBF Ford application. 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
