An often forgotten component, but extremely important
one for performance!
The distributor handles several jobs. It?s
first job is to distribute the high voltage from the coil to the correct
cylinder. This is done by the cap and rotor. The
coil is connected to the rotor, which spins inside the cap. The
rotor spins past a series of contacts, one contact per cylinder. As
the tip of the rotor passes each contact, a high-voltage pulse comes from
the coil. The pulse arcs across the small gap between the rotor and
the contact (they don?t actually touch) and then continues down the spark
plug wire to the spark plug on the appropriate cylinder.
When you do a tune-up, one of the things you replace
on your engine is the cap (Part#) and rotor (Part#) these
eventually wear out because of arcing. Also, the spark-plug wires
(Part# or#) eventually wear out and lose some of their
electrical insulation.

Spark timing is so critical to an engine?s
performance, and the timing can either be advanced or |
 |
retarded depending
on conditions. The time that the fuel takes to burn is roughly constant.
But the speed of the pistons increases as the engine speed increases.
This means that the faster the engine goes, the earlier the spark has to
occur. This is called spark advance: the faster the engine speed,
the more advance is required typically.
LC Engineering Pro Distributor's (Part# &
#) provide an increase in horsepower and acceleration do to a
performance ignition curve. However, in order to achieve top performance,
it is imperative that the installation and timing be set correctly. The
Pro Distributors are set with a 20
@ 2000 rpm curve. The best way to time these units is to find TDC on the
#1 piston and install the distributor

initial timing. You will then have 30
to 32 total degrees of timing @
2000 rpm's. Street engines with
lower compression ratios can increase total timing between 36 and 38,
beware of pre-detonation! |

Some users will like to advance or retard timing, as
each motor is different (i.e. compression ratio, head milling, etc).
