These new 85 Series HEI distributors from Mallory feature a CNC-machined cast 356 T-6 aluminum upper housing with a billet lower housing for lightweight durability. They include Mallory's new mechanical advance mechanism and adjustable vacuum advance and come with a red cap and rotor with brass inserts. They're direct plug-in replacements with OE factory-type harness connectors (Chevrolet versions only) and are available with or without Mallory's high performance coil. You can also get them in a Race Prepped version that features a locked-out mechanical advance, a locked-out vacuum advance with the chamber removed, and a complete advance weight and spring kit to allow for mechanical advance conversion. These new 85 Series HEI distributors also come with a steel distributor gear to work with a flat tappet or hydraulic roller cam motor.
