GENERAL INFORMATION

Mechanical Advance

Distributor part numbers ending in “1” have 24° (crankshaft degrees)

of mechanical advance. Distributors ending in “05” have 20° (crank-

shaft degrees) of mechanical advance. Both of these may be adjusted

by using Mallory Advance Curve Kit 29014 to fine tune the curve to

your particular engine’s requirements.

Distributor part numbers ending in “04” have locked, 0°, mechanical

advance.

Electronic Ignition Controls

These distributors require the use of a Mallory HYFIRE 6 or 7 Series

Capacitive Discharge Ignition System or a similar type CD ignition.

They cannot be used with just a coil.

Ignition Coils

Use ignition coils recommended by the ignition coil manufacturer for the

particular electronic ignition control.

Spark Plug Wires

YOU MUST USE suppression type (carbon core; spiral core;

suppression core) spark plug wire. We recommend spiral core ig-

pression type spark plug wires prevent false triggering and the possi-

bility of premature ignition or accessory failures.

DO NOT USE solid core (copper core; stainless steel core)

spark plug wire with any electronic ignition system or acces-

sory. Solid core spark plug wire causes radio frequency interference

(ignition noise; static). Radio frequency interference causes false trig-

gering (pre-ignition; spark-scatter) and premature ignition or accessory

failures. Prevent false triggering and the possibility of premature ignition

or accessory failures, use suppression type spark plug wire (carbon

core; spiral core; suppression core). We recommend spiral core igni-

Spark Plug Gaps

Experiment with and closely monitor various gaps to achieve maximum

performance. Exceptionally large spark plug gaps lead to problems of

crossfire inside the distributor cap, burnt rotors, spark plug wire failure

and reduced spark plug life. If you are trying to find the ideal spark

plug gap, start at 0.035" and increase 0.005" at a time until elapse

times fall off (or MPH-falls off), the car starts misfiring or the incidence of

failure to the distributor cap, rotor, spark plug wires or spark plugs is

frequent during the race.

Electric Welding

Unplug the distributor wire harness before welding on the vehicle.

Distributor Drive Gear

Bronze distributor gears absorb the increased wear caused by special-

ized camshafts and are easily replaced before costly damage to the cam-

shaft gear occurs. Bronze distributor gears must be checked frequently

and replaced often and are metallurgically compatible with any camshaft.

OLD DISTRIBUTOR REMOVAL

Step 1

Locate the #1 cylinder’s spark plug wire on the original distributor cap.

Mark the distributor cap and the distributor housing, in line with this spark

plug wire position on the distributor cap.

Step 2

Turn the engine crankshaft in the direction of rotation until the timing mark

lines up with the top dead center (TDC) mark on the timing tab.

NOTE: Removing the spark plugs may make it easier to turn

the crankshaft.

Step 3

Remove the distributor cap from the distributor. Do not remove the spark

plug wires or coil wire at this time. The rotor blade should point to the

mark made on the distributor housing (from Step 2). If it is not, turn the en-

gine crankshaft in the direction of rotation one full turn (repeating Step 3)

until the timing mark lines up (again) with the TDC-mark on the timing tab.

NOTE: Once you are finished with step 4, do not turn the

crankshaft until the new distributor is installed.

Step 4

Note the direction the rotor is pointing. If you are replacing a vacuum ad-

vance distributor, disconnect the vacuum hose and plug the source. Re-

move the distributor hold down clamp and remove the distributor from the

engine.
