FAST XDi HEI Distributor for Chevrolet Small Block & Big Block

The FAST XDi Street HEI Distributor is packed with high-performance features, making it the perfect choice for any Small or Big Block Chevy engine. Featuring a powerful 6-amp ignition module that drives a custom-wound performance coil up to 50,000+ volts, it provides the hot spark needed for maximum horsepower. These distributors also come equipped with a heat-treated steel gear that is compatible with popular camshaft materials. While perfect as a drop-in, ready-to-run distributor, additional lightweight advance springs and an adjustable vacuum advance are included for those who like to custom tune for extra power and throttle response.
