The "rotor" head is attached to the top of the distributor shaft which is driven by a gear on the engine's camshaft and thus synchronized to it. This rotor is pressed against a carbon brush on the center terminal of the distributor cap which connects to the ignition coil either through the top and wired directly to the coil in HEI systems, or via the center terminal in points ignition systems and remotely connected to the coil.

The rotor is constructed such that the center tab is electrically connected to its outer edge so that voltage coming in to the center post travels through the carbon point to the outer edge of the rotor. As the camshaft rotates, the rotor spins and its outer edge passes each of the internal plug terminals to fire each spark plug.

Replacing that worn out distributor has never been easier with the Perma-Tune distributor for the 356 engine

Distributors wear out and rob your engine of the horsepower it was intended to produce. Worse yet, they can leave you stranded or even damage the crankshaft ring gear.
Forget about rebuilding an outdated distributor with hard to find parts when you can replace it with modern technology that looks original. There are no wires to cut and splice: the distributor has the electrical harness built in and features the original equipment compatible connectors for a plug and play installation.

Simply mount the ignition module to the relay panel where the later model cars had the module mounted and then plug the distributor harness connector into the Perma-Tune module. The power, ground, tachometer and coil connections are made at the existing coil wires. The harness has loop connections that allow joining the wires without having to cut and splice the car harness wires.
The Perma-Tune distributor harness is made using the same vinyl sleeve loom construction as the original wiring for that factory original look.

This Perma-Tune Porsche distributor is an exact fit replacement part that will drop right into the engine. Setting the static timing is easy with the built in trigger point LED that lets you know when the rotor is pointing in the right direction.
Idle timing is set in exactly the same way as the factory manual indicates and the factory mechanical and vacuum curves are preprogrammed into the distributor. The mechanical vacuum can is replaced with a reliable MAP sensor that is fully programmable to perform advance or retard vacuum functions.
It just doesn't get any easier than this.

This is where the fun starts
Street tune your car for maximum performance using your smart phone.
Download the free TUNE + app to your phone and connect it to the Perma-Tune distributor via Bluetooth.
Using the TUNE + app, you can read and store the ignition curves, modify them and share them with others. The app even has an ignition lock feature that prevents unauthorized use of the car. Do more than just a onetime engine tuning. Engine programs are so easy to create and load into the car that you can make your own library of programs for different uses.
For instance, you could create a de-tuned engine program for a novice driver, a super tune program for yourself or a valet tune program for the parking attendant. Get the most from engine upgrades like headers, intake, and many other engine modifications by creating custom ignition maps.
The possibilities are endless.

Point Contact Breaker.
Restore reliable ignition switching and consistent engine operation with this Porsche Point Contact Breaker. Designed for compatible classic Porsche ignition systems, the contact breaker—commonly known as ignition points, contact points or breaker points—is a key mechanical component within the distributor.

Fits:

Diagram Ref No 23

In a traditional points-based ignition system, the distributor cam repeatedly opens and closes the contact breaker as the engine rotates. This switching controls current through the ignition coil. When the points open, the magnetic field in the coil collapses, generating the high voltage required to produce a spark at the spark plugs.

Because the contact surfaces open and close thousands of times during normal engine operation, they gradually wear. Electrical arcing can cause pitting or burning of the contacts, while mechanical wear can alter the points gap and ignition dwell angle.

Correctly adjusted, serviceable contact points are essential for reliable starting, smooth running and accurate ignition performance. Replacing worn points with the correct Porsche Point Contact Breaker 61660222603 helps restore dependable ignition switching and provides a sound basis for correct distributor adjustment.

What This Product Does:

• Mechanically switches the ignition coil primary circuit.
• Opens and closes as the distributor cam rotates.
• Controls the timing of ignition coil charging and discharge.
• Allows the ignition coil to generate the high voltage required for the spark plugs.
• Helps maintain the correct ignition dwell when properly adjusted.
• Supports reliable engine starting.
• Helps maintain smooth idle and consistent engine operation.
• Supports correct ignition performance throughout the engine speed range.
• Works together with the distributor, ignition coil and condenser.
• Provides a serviceable component for traditional mechanical ignition systems.
• Replaces worn, burned, pitted or incorrectly operating contact points.
• Helps maintain the original-style ignition system on compatible classic Porsche models.  

Symptoms Of Wear Or Failure:

• Difficult starting.
• Engine cranking but failing to start.
• Intermittent starting problems.
• Rough or unstable idle.
• Engine misfires.
• Hesitation during acceleration.
• Poor throttle response.
• Loss of engine power.
• Engine cutting out intermittently.
• Poor running at higher engine speeds.
• Inconsistent ignition timing.
• Excessive electrical arcing at the points.
• Burned or blackened contact surfaces.
• Pitting or material transfer between the contacts.
• Incorrect or continually changing points gap.
• Excessive wear of the rubbing block.
• Weak or inconsistent ignition spark.
• Increased fuel consumption caused by poor ignition performance.  

Why Replacement Matters:

• The contact breaker is central to the operation of a conventional mechanical ignition system. If the points cannot switch the ignition coil correctly, spark quality and ignition timing can deteriorate.
• As the contact surfaces become burned or pitted, electrical resistance can increase and switching can become less consistent. This may reduce the effectiveness of the ignition system and contribute to misfires or difficult starting.
• Mechanical wear is equally important. The rubbing block follows the distributor cam and determines when the contacts open. As this surface wears, the points gap and dwell angle can change.
• An incorrect points gap can alter ignition performance and timing. Too little or too much dwell can affect how effectively the ignition coil charges between firing events.
• Replacing worn points with a correct Porsche Point Contact Breaker 61660222603 helps restore precise mechanical switching, reliable spark generation and consistent engine performance.
