The EFI Hi-Ram manifold line has a new addition for the 8.2 in. 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 in. deck height.

Instructions for Part# 300-274
*** Please see the diagrams in the product images for other dimensions.<br>*** A low profile distributor will be needed when using this manifold. Holley has a Sniper Hyperspark version #565-322 and a Holley EFI Dual Sync #565-211 available.<br>Warning:<br>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.
