MSD - Includes vacuum advance and must be used with an MSD 6, 7 and 8-series ignition.

The Street Pro-Billet is a popular route for people looking for proven race performance for their street cars. A vacuum advance canister provides economy and the proven MSD mechanical advance gives you the opportunity to dial-in a timing curve to fit your needs. Inside, an oversized steel shaft is QPQ-coated for low friction and rides in a sealed ball bearing at the top of the distributor with an extra-long sintered bushing at the bottom. This combination keeps the shaft steady creating accurate spark delivery at any rpm.
