MSD 83891 Pro-Billet Distributor for Chrysler 392 HEMI

The MSD 83891 Pro-Billet Distributor is purpose-built for vintage Chrysler 392 HEMI engines, delivering the precision ignition timing and trigger accuracy that classic HEMI builders demand. The housing is CNC-machined from billet aluminum for exceptional strength and tight manufacturing tolerances, while the distributor shaft rides on a sealed ball bearing for smooth, accurate operation at any RPM.

Tuning the ignition curve is straightforward thanks to MSD's easy-to-adjust mechanical advance system. The distributor ships with an assortment of advance springs and stop bushings, allowing you to dial in a custom timing curve that matches your specific engine build and application. A vacuum advance canister is also included to improve throttle response and fuel economy during part-throttle cruising.

• Pro-Billet distributor with CNC-machined billet aluminum housing
