No advance assembly, the rotor plate is welded directly to the oversized shaft keeping the timing and spark ready at any RPM. 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"e;) bronze gear is installed along with an adjustable slip collar for modified blocks, heads or intake manifolds.
