The EFI Hi-Ram manifold line has a new addition for the 351W Ford application. The new manifold is available to work with a 95MM or 105MM LS throttle body. 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. These manifold kits come with billet fuel rails. The fuel rails are setup to use -8AN o-ring fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsation in the fuel system. This manifold is the perfect addition to your EFI combination. Available separately, Holley has also designed a low profile 351W dual phase distributor for this combination. (Part Number 565-111). The new distributor allows for proper spark plug wire clearance under the intake and it can also be used with coil on plug applications. Also a replacement fuel rail kit, 534-234 is available for the 351W Hi-Ram manifolds.
