Holley EFI Releases Black 351W Hi-Ram Manifolds
Holley/MSD is pleased to announce the release of Holley EFI Black 351W Hi-Ram Manifolds, which 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 just 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.

How To Choose A Drag Race Ignition| 12/03/2018
Drag racers rely on exotic fuels and high cylinder pressures to make huge power. High compression ratios, nitrous oxide and high boost pressures paired with alcohol, methanol or nitro make lighting the air/fuel mixture in the cylinder difficult. The immense pressures inside the combustion chamber will literally blow the spark out. This is where an MSD ignition really shines. Its ability to fire the most powerful and fastest racecars on the planet is legendary. MSD ignition systems can be basic, or advanced enough to control one-tenth of a degree of timing for one-hundredth of a second in any cylinder using individual cylinder timing.
