This Holley HyperSpark distributor drops into a Holden 253 / 304 / 308ci application as a plug-and-play upgrade alongside Sniper EFI and other HyperSpark ignition components. The CNC billet aluminum housing and billet-machined shutter wheel are built to hold timing accuracy at high RPM, and a single Hall Effect sensor keeps the RPM signal free of interference. A patented clear installation cap simplifies setup, and the distributor ships with a wire retainer for spark plug wires and Lucas Racing Performance Gear Break-In Lubricant.
