Now More Distributor Choices!

  • Holley HyperSpark Distributor: The new kid on the block. A hall-effect crank sensor and killer pricing makes this an amazing choice for Sniper EFI Fuel Injection Systems or any aftermarket EFI system that does not require a cam sensor
  • Holley Dual Sync Distributor: The tried and trusted warrior. This incredible distributor features both crank and cam hall effect distributors, making it ideal for applications that require both for synchronous fuel injection or coil-on-plug ignition setups. Also works with the Sniper EFI System where no HyperSpark distributor is available (requires 558-493 Adapter Harness when used with Sniper EFI System.)
  • Distributor Accessories: We carry everything you need to go with your EFI distributor--from coils and ignition boxes to adapter harnesses and replacement caps and rotors.

More on EFI Distributors

A high quality Holley EFI Dual-Sync Distributor will make your EFI installation as smooth as butter. Normally, providing timing to the ECU and then setting up the ECU to provide timed ignition pulses back to the engine is one of the most complex parts of an EFI system installation. These distributors make that process completely plug-and-play.

The Holley EFI ECU is incredibly adaptable, for sure. All it needs to operate is an RPM signal. From that it can provide basic paired- or bank-to-bank fuel injection strategies. To do full sequential fuel injection, it is necessary to provide the ECU not only with RPM but also identify the piston that is firing. Since the crankshaft revolves twice for each cam location, it is necessary to sync the ECU with both the crank and the camshaft. A dual-sync distributor does that for you.

But providing the engine timing is only half the job of the Holley Dual-Sync Distributor. Since it allows electronically-adjustable ignition timing all this allows the Holley EFI ECU to control the timing.

So, how hard is it to install one of these Holley Dual-Sync distributors? Well, provided one is available for your engine, you simply drop it into the distributor shaft hole in the engine and click the 10-pin connector on the distributor to the matching connector on the Holley EFI Main Harness. You're almost done. Simply follow the straight-forward directions that come with the distributor for aligning the distributor and setting it up in the Holley EFI laptop software. You're done. No crimping, no guessing which wire is which.

Installing a Holley Dual-Sync Distributor with a Holley Sniper EFI System?  Perfect!  You will need to add the Holley Sniper to Dual Sync Distributor Adapter Harness.

Are you installing your Holley Dual-Sync DIstributor on a billet steel camshaft with a billet steel distributor drive gear?  Then be sure to switch to this MSD Bronze 0.500-inch Distributor Gear.

In the event you wanted to run Coil-On-Plug ignition you can order the COP Blanking Cap to replace the normal distributor cap. No more does COP mean you have to fuss with adding crank and cam sensors. And since you do have a cam sensor it means you don't have to run waste-spark. This is truly a slam-dunk decision.
