MSD Ignition 85501 Pro-Billet Distributor for Chevy V8

This strong, billet aluminum distributor is set up for engines that run locked-out timing or an MSD Timing Computer. With no advance assembly, the rotor plate is welded directly to the oversized shaft. A sealed ball bearing guides the top of the shaft while an extra long sintered bushing stabilizes the lower portion.\nTrigger signals are produced via a high-output magnetic pick-up. This pickup is extremely accurate and never requires adjustment. Since this distributor is designed primarily for race engines, an oversized (+.006") bronze gear is installed along with an adjustable slip collar for modified blocks, heads or intake manifolds.
