These Pro-Billet Ready-to-Run distributors from MSD are the perfect upgrade for weak OE electronic distributors, outdated points distributors, and large HEIs or DuraSparks. All that is required is to install the distributor in the engine, and connect three wires and the coil! A maintenance-free magnetic pickup accurately triggers this ignition with increased output from the amplifier, easily outperforming stock ignitions. It will smooth out the engine's idle, improve starting, and perform at a much higher rpm. The housing is machined from billet 6061-T6 aluminum, using state-of-the-art CNC mills and lathes for a housing with no porosity or weak areas. For stability and endurance, an oversized steel shaft spins in a top-mounted sealed ball bearing, while an extra-long sintered bushing guides the shaft at the base of the housing. This shaft also receives a QPQ coating for low friction wear and resistance against corrosion from humidity and ozone buildup. They feature MSD's adjustable mechanical advance, which allows you to custom-tailor an ignition curve to match your engine's needs. Most models are also available with a vacuum advance canister to help improve economy.
