Billet Chevy Small and Big Block V8 Distributor by MSD Ignition

This is MSD's most popular Chevrolet distributor and is engineered for performance from the inside out! The 0.500" steel shaft receives a Tuftride coating for friction reduction and resistance to corrosion. A combination of a sealed ball bearing and an extra long sintered bushing provide smooth operation at high rpm. The MSD high output magnetic pickup produces a trigger signal as the paddles of a precision manufactured reluctor spin by. This pickup is also maintenance-free with no adjustments ever necessary! Above the pickup is the mechanical advance assembly. Different springs and bushings are supplied so you can dial-in an advance curve quickly and easily. The assembly is made up of chrome moly weights that slide on nylon bushings. The weight pins are staked and tig welded for incredible strength. The housing is CNC machined from 6061-T6 aluminum and features an oil lube tract to direct oil to the cam and distributor gears. For modified blocks, there are two o-ring grooves that will keep the oil from leaking down from the oil gallery. The distributor comes complete with a high quality cap and MSD's Racing Rotor. There is no vacuum advance and an MSD Ignition Control must be used.
