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. The Street Pro-Billet relies on a magnetic pick-up to trigger the MSD Ignition Control which delivers the powerful sparks to the coil. This pick-up is extremely accurate and never needs adjusting.
