Description
If you’re running an MSD Pro Billet or Ready to Run distributor with vacuum advance, a worn or failed canister will throw off your ignition timing and rob you of consistent performance. The MSD 8463 Vacuum Advance Mechanism restores precise timing control, ensuring your engine delivers the power and efficiency it’s capable of. This is a direct replacement that bolts in without fabrication—ideal for racers and enthusiasts who need reliability on and off the track.
