Corvette owners can now replace their worn out Magna-Pulse distributors with this precision Pro-Billet Tach Drive Distributor. Advantages such as an accurate magnetic pick-up, oversized shaft, vacuum advance and a billet aluminum housing are just a few of the MSD advantages. Inside the billet housing, a sealed ball bearing and long sintered bushing guide a 0.500\" steel shaft for high rpm accuracy. A special reluctor is mounted to this shaft and is responsible for triggering the magnetic pick-up. The tach drive assembly is compact to clear the firewall and linkage. It can be repositioned easily to fit different applications plus has a grease fitting for lubrication.\u003c\/p\u003e\u003ch3\u003eFeatures:\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSame features as the PN 8571 with the addition of a vacuum advance\u003c\/li\u003e\n\u003cli\u003eCARB E.O.
