MSD Distributor P/N:85583

Route high-voltage spark to the plugs with the MSD Crank Trigger Distributor 85583, a billet low-profile unit built for the Chevy V8 tall block. Its low, tight profile is designed to fit tight intake systems and clear firewall/intake combinations while carrying the high voltage of an MSD racing ignition. This is a crank-trigger distributor, so it must be used with an MSD crank trigger and an MSD ignition control. It fits a wide range of 1955-1975 Chevrolet, GMC and Pontiac applications — including the Chevrolet Bel Air, Camaro, Chevelle, Impala, Nova and C10 Pickup, the GMC C15/C1500 Pickup and Jimmy, and the Pontiac Ventura. See the Buyer's Guide tab for the full 52-application list.

• Low-profile billet housing: CNC-machined billet aluminum with a high-dielectric DuPont Rynite base that helps prevent arcing to the housing.
• Large-diameter HEI-style cap and rotor: wide-spaced terminals with an injection-molded Rynite rotor featuring thick vanes to stir the air inside the cap; supplied with a black cap.
• Tall-block slip collar: an adjustable slip-collar mounting flange lets it fit most tall-block engines with modified deck heights.
• Oversized shaft: QPQ-coated polished steel shaft guided by sealed ball bearings, with a special oil tract to improve lubrication to the distributor/cam gear.

Supplied with a bronze gear. O-ring seals can be installed for oil pressure control (modified engines only).
