1971 GMC C25/C2500 Suburban Performance Distributors

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.

The unique design of these distributors fit tight intake systems while still transferring the high voltage of the MSD racing ignition to the spark plugs. The high voltage carrying capabilities are the result of several features which have been designed into these low-profile distributors. This includes a large diameter cap with wide spaced terminals and an injection molded Rynite rotor with thick vanes to stir up the air inside the cap. The high dielectric Rynite base also prevents arcing to the billet housing. Since these distributors are used primarily in racing applications, an oversized steel shaft is responsible for delivering the sparks. This shaft is QPQ coated for friction reduction and receives guidance from a sealed ball-bearing assembly and an extra long, precision sintered bushing for smooth operation. Note: must be used with an MSD crank trigger and ignition control.
