use a suppression type spark plug wire. Failure to use the correct wires will cause
electrical interference with the Engine Control Module.

When installing the distributor, make sure to disconnect the vehicle’s battery BEFORE
beginning the installation.

If the drive gear is ever replaced, you must use a MSD #8531 distributor drive gear
due to the .500” diameter drive shaft.

INSTALLATION PROCEDURE
1. Loosen the adjustable slip collar, Install the Distributor into the engine without the
gasket installed, make sure the oil pump shaft is fully engaged, slide the slip the collar
down to sit against the manifold. Tighten the collar and remove the distributor. Tighten
the set screws on the collar and install the gasket.
2. Rotate the crankshaft in the direction of normal rotation until cylinder #1 is coming up
on the compression stroke. Stop turning when the crankshaft is at 22° BTDC.
3. Install the distributor, with gasket and cam gear lubricated, so that the rotor comes to
rest pointing at what will be the #1 terminal on the cap. Position the cap such that #1
is in the Location shown on the drawing below. You may need to remove and reinsert
the distributor a few times to get the alignment correct. Make sure that the distributor
seats down completely and has fully engaged the oil pump drive. You may need to
rotate the oil pump shaft to ensure it is engaged properly.
4. Lift the rotor by hand to make sure that there is adequate end play. Lack of end play
indicates that the rotor shaft is bottomed out on the oil pump shaft. If there is no end
play readjust the Slip Collar as mentioned above.
5. Align Distributor cap clips parallel with the firewall, Hall Effect sensor should be
pointing toward the forward drivers side of the engine. See Figure 14.
6. Tighten Distributor hold down clamp.
