    MSD 8479 Details

    The Street Pro-Billet Distributors are the perfect choice for powerful engines that see plenty of street time. The Street models share the same features as the small diameter models shown above, plus feature a vacuum advance. This canister provides improved economy and an accurate mechanical advance lets you dial-in an advance curve to match your driving needs. A magnetic pick-up produces accurate trigger signals that remain stable throughout the entire rpm range of your engine and is completely maintenance-free.
