Firewall clearance, a tall intake or a cowl-mounted brake booster can make a conventional distributor impossible to install. This is the smallest diameter Chevy distributor in the line, measuring a half inch smaller across and over an inch shorter than a standard points-cap unit, while keeping the high output magnetic pickup and adjustable mechanical advance of the full-size versions.

MSD 85701 Small Diameter Pro-Billet Distributor Features:

• CNC machined billet aluminum housing sized for tight clearance installations.
• Must be used with a 6, 7, 8 or 10 Series ignition control.
• High output magnetic pickup with precision machined reluctor.
• Fully adjustable mechanical advance with supplied springs and stop bushings, and it can be locked out for crank trigger use.
• Adjustable slip collar mounting flange for engines with modified deck heights.
• Polished QPQ coated shaft on a sealed ball bearing and extra-long sintered bushing.
• Small diameter HEI style cap and rotor included. Will not accept a vacuum advance canister.
