XDi Race EFI Distributors, Small Block & Big Block Chevrolet, Large Cap

The FAST® Large Cap XDi Race EFI Distributor for Small and Big Block Chevy engines 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.
