Distributor Removal and Installation
1. Remove #1 spark plug and pull the coil wire off
2. Place your finger over the spark plug hole
3. Have an assistant bump the motor over until you feel air pushing
your finger off the hole.
4. Use a socket (1.25" usually) and manually bring the engine dampener
mark to zero.
5. Remove the distributor cap, the rotor should be pointing in the general
vicinity of #1 cylinder.
6. Note the location of the vacuum canister.
7. Remove the distributor and write your name on it with a Sharpee.
8. Do not rotate the engine, leave it right where it is.
1. Clock the rotor so it's pointing at #1 cylinder and hold the housing
so the vacuum unit or cover plate is in the approximate position as in #6
2. Drop the distributor in and jiggle the rotor and housing slightly
until it drop into the oil pump drive, be sure that it drop all the way down.
3. Determine the correct rotation of your distributor, SB Mopars rotate
clock wise, 383/400/440 all rotate counter clockwise.
4. Look at the reluctor (Star wheel on your distributor shaft) see
#6 above and turn the housing to the approximate location, one of the paddles
on the reluctor should now be very close to the magnetic pickup center. Adjust
it now so it lines up dead center on that contact point.
5. You now have set the distributor to zero timing and the rotor should
line up centered on the cap contact for #1 plug wire. You can use a
Sharpee to mark the housing so when you position the cap it's easy to confirm
that #1 cap terminal is directly in line with the rotor.
6. Of course at Zero timing the motor will have a hard time starting
so we need to advance it to about 15*-20* , so if we think about this the
position we have it set at the distributor should have already fired #1 plug
so study your rotation and think about which direction it rotates and
turn the housing so that it indicates that the distributor has already
fired #1. On a Clockwise distributor (SB) you would turn the housing
COUNTER CLOCKWISE a BB you would turn the housing the opposite direction.
Always remember that "Rotation Retards" so to advance the timing you
turn it counter rotation.
7. How far?
Just rotate the distributor to about 1/8 to 3/16" past the contact point
with the reluctor paddle, this will put enough timing in the motor to fire
it off, even close will fire the motor and allow for final tuning with a
good timing light. see #6 for correct direction to rotate the housing.
8. Snug down the clamp just enough so you can grab the cap and turn
the distributor with a strong arm, we just don't want it to slip when we're
trying to start it and time it.
9. Turn the key and light it off, bring it up to temp and set the initial
timing as per your specs. We recommend that you also bring it up to
about 100-200 RPM above where we set the total at and with a dial back light
check to be sure that it doesn't exceed the total timing we have determined
as Max timing for your application.
10. Your all done, tighten down the distributor clamp, double check
it and "Happy Motoring"
Poor wires or a bad cap will load your body with about 25,000 volts
at idle if using our ignition system and remove all doubt that our ignition
system puts out extreme voltage. Be sure the entire system is in top
condition before grabbing a handful of ignition wires, failure to do so may
cause your head to slam into the hood and or painful bruising of the elbow
when it makes rapid contact with the inner fender.
