Description
MSD Pro-Billet Street distributors are a popular choice for those who desire race-proven performance for their street machine. A vacuum advance canister provides improved economy, and the proven MSD mechanical advance mechanism allows dialing in a timing curve as desired. An advance kit of springs and stop bushings is included. The housing features an all-billet 6061-T6 aluminum design for accuracy to within .001 in. An oversized steel shaft is QPQ-coated for low friction, and rides in sealed ball bearings at the top and bottom of the distributor. An extra-long sintered bushing replaces the ball bearing at the bottom for Chevrolet models. This combination keeps the shaft steady, creating accurate spark delivery at any RPM. They rely on a magnetic pickup to trigger the MSD ignition control, which delivers the powerful sparks to the coil. This pickup is extremely accurate and never needs adjusting. The distributors are CARB E.O. approved for use in all 50 states, and are guaranteed to deliver race-quality performance. These distributors require the use of a separate ignition box, such as an MSD 6, 7, 8, or 10 Series ignition.
