XDi Race EFI Distributor, Small Block & Big Block Chevrolet, Small Cap

The FAST® Small Cap XDi Race EFI Distributor for Big and Small Block Chevrolets allows the proper triggering of all EFI systems without compromising rotor phasing, for the most stable ignition timing throughout the entire RPM range. The distributor uses an advanced optical trigger to deliver more precise trigger signals (± ½-degree accuracy) than magnetic pickups used by competitors, particularly at high RPM.


The FAST® XDi Race EFI Distributor is constructed with a CNC-machined billet housing, a precision-ground stainless shaft and premium bearings, all hand-assembled to exact standards. This maintains a consistent end play that eliminates another common source of timing fluctuation. Each distributor comes with a high-quality rotor and precision-machined bronze gear.
