MSD Pro-Billet HEI Distributor for Chevy V8 Engines with Vacuum Advance 8365

If you're running a Chevy V8 without a modern ignition system, you're leaving performance on the table. The MSD Pro-Billet HEI Distributor delivers reliable spark timing and superior engine response with zero maintenance—no points, no caps to adjust, just plug-and-play performance. Built from CNC-machined billet aluminum, this distributor handles the demands of street engines and mild builds without breaking down.

The magnetic pickup eliminates timing drift across RPM ranges, while the integrated vacuum advance automatically optimizes ignition timing under varying load conditions. Since no external ignition box is required, installation is straightforward on most Chevy V8 platforms. Whether you're tuning a classic rebuild or upgrading tired stock electronics, this distributor provides the accuracy that matters when consistency counts.
