Holley/MSD has announced the expansion of its line of EFI Hi-Ram intake manifolds to include 351W Ford engines. Compatible with both 95mm and 105 mm throttle bodies, they feature a tapered cross-section design and runner lengths ideal for a wide range of engine combinations. The water crossover passage has been redesigned to allow extra room for distributor phasing. Both manifold kits come complete with billet fuel rails set up to use -8AN O-ring fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsation in the fuel system.
Holley has also developed a low-profile 351W dual-phase distributor specifically for this combination (part number 565-111). This compact, all-new distributor is designed to allow for proper spark plug wire clearance under the intake and is also compatible with coil-on-plug applications. It includes dual Hall Effect sensors for crank and cam signals, can be used as just a crank speed input, and provides a cam-sync signal for sequential fueling operation. A billet blank Holley EFI cap is also available for coil-on-plug applications (part number 566-103).
