GM HEI Replacement Distributor

The ACCEL GM HEI Replacement Distributor is a high-performance billet distributor designed for small-block and big-block Chevy V8 engines that require reliable ignition timing control. This unit serves as a direct replacement for factory HEI distributors, ensuring consistent spark delivery and precise dwell management for various applications, including street, strip, and restoration.

Featuring a magnetic pickup ignition system, this distributor offers superior reliability compared to points-based designs by eliminating contact wear and providing consistent dwell curves across RPM ranges. The vacuum advance mechanism allows for automatic ignition timing adjustments based on engine load, optimizing fuel efficiency and reducing emissions during partial throttle conditions. Constructed from durable billet aluminum, the housing is resistant to corrosion and thermal stress, while the HEI-style terminal configuration ensures seamless integration with existing plug wires and coil packs.

Ideal for engine rebuilds, performance upgrades, or maintenance replacements, the GM HEI Replacement Distributor is compatible with all standard small-block and big-block Chevy V8 engines that have HEI distributor mounting provisions. Installation is straightforward, requiring no frame modifications—simply remove the old unit and bolt in the new distributor using existing engine components.
