LC Pro Distributor
 

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#17-901) and rotor (Part#17-902) – these eventually wear out because of arcing.  Also, the spark-plug wires (Part#17-104 or#17-103) eventually wear out and lose some of their electrical insulation.

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#17-100 & #17-100V) 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
