If your race car requires a distributor with a mechanical tach drive, this is the one you need. The PN 8571 Tach Drive Distributor has all of the same features as the Corvette Distributor, except it does not have a vacuum advance.

Our race proven magnetic pickup delivers precise trigger signals to your MSD Ignition every time one of the reluctor's precision paddles pass by. This reluctor assembly is connected to an oversized steel shaft for increased strength and endurance.

Just above the reluctor, a mechanical advance assembly provides the ability to produce a timing curve to match your engine's needs. This assembly is tig welded for strength and features chrome moly weights and nylon pads to ensure smooth advance as the rpm increases.

The PN 8454 Billet Distributor shares all of the above features, plus has an adjustable slip collar for engines that have had the deck height modified or use exotic intake manifolds. The distributor also features a Rynite™ base.

NOTE: Must be used with an MSD 6, 7, 8 or 10 Series Ignition. Supplied with a Cap and Rotor.
