MSD Chevy V8 Pro-Billet Distributor - 85501

Locked-out from the factory. Must be used with an MSD 6, 7 or 8-series ignition.

Part Number: 85501

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.
Trigger 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.
