Important:
Read these instructions before attempting the installation.
P a r t s I n c l u d e d :
1 - Pro-Billet Distributor
1 - Rotor, PN 8467
1 - Distributor Cap, PN 8433

Note: The terminals of this Distributor require spark plug style terminals. You may need to change
the terminals and boots of your wires. MSD offers two kits, PN 8849 or PN 8848, that are supplied
with nine boots and terminals.
Note: If the gear is ever replaced, an MSD Gear is required for replacement due to the .500" diameter
shaft. PN 8531 is iron, PN 8471 is bronze.
Note: An MSD Ignition Control must be used with each pickup.
TIMING FUNCTIONS
Before continuing with the installation, here are a few definitions you should be aware of:
Initial Timing: This is the base timing (also referred to as idle timing) of the engine before the
centrifugal advance begins.
Centrifugal Advance: The centrifugal (or mechanical) advance mechanism is made up of weights,
springs, advance cams, and an advance stop bushing. The amount and rate of advance that your
distributor is capable of is determined by the centrifugal timing. If you ever wish to lock out the
centrifugal advance, refer to the centrifugal advance section.
Total Timing: This is the total of the initial timing plus the centrifugal advance added together.
Example: 10° Initial + 25° centrifugal = 35° Total Timing. (When checking Total timing, disconnect
the vacuum canister and plug the vacuum source.)
Note: MSD Distributors are supplied with the heavy (slow) advance springs installed. This is to
prevent detonation in certain applications. Review the information on pages 2-4 to determine
the best advance curve for your application.
WARNING: Before installing the MSD Distributor, disconnect the battery cables. When
disconnecting the battery cables, always remove the Negative (-) cable
first and install it last.
