Holley EFI has announced its 351W Hi-Ram Manifolds are now available in black. Originally launched in a satin finish, these intake manifolds feature a tapered cross-section design and runner lengths to suit countless different applications.
Available in two versions – one to fit 95mm throttle bodies and one for 105mm throttle bodies – they feature completely redesigned water-crossover passages that create additional room to make distributor phasing easier. Both kits come with matching black-anodized billet aluminum fuel rails large enough to handle high fuel flow while dampening pressure pulsation throughout the fuel system.Also available are two 351W manifold bases and a low-profile dual-phase distributor developed just for these manifolds. Both the EFI manifold base and the carburetor base are of billet aluminum construction and anodized black. The distributor is specially designed for maximum spark plug wire clearance under the intake and features dual Hall Effect sensors for crank and cam signals and a cam-sync signal.
