The EFI Hi-Ram manifold line has a new addition for the 351W Ford application. This manifold comes with a 95MM LS throttle body flange top, a 105mm LS throttle body top is also available. 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 9.5" deck height.

Manifold Width is 11.32".

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.
