Octane adjustment Rod????
Anybody "Really know what's going on" w/ these?
The octane rod adds a provision for a fixed octane adjustment. The adjustment is done by replacing the standard zero-degree rod located in the distributor bowl with a three degree or six degree retard rod. This is done only if the engine is experiencing a pinging or engine knocking condition and can not be repaired with the conventional methods (timing adjusted, proper operating temperature, higher gasoline octane rating....etc).
OCTANE
ISSUE:Rough idle, hesitation, poor throttle response, induction backfire and stalls during cold start/warm up may be caused by the poor volatility of some high octane premium grade unleaded fuels (91 octane or higher (R+M)/2). When compared to regular grade unleaded fuel (87 octane (R+M)/2), high octane premium grade unleaded fuel may cause long crank time.
ACTION: Use a regular grade unleaded fuel in all vehicles, except where a premium unleaded fuel is recommended in the Owner Guide. If lean air-fuel type symptoms are experienced, determine the grade and brand of fuel used and offer the following service tips.
^ Advise those using a higher octane grade fuel to switch to a regular grade unleaded fuel. For those using a regular grade fuel, advise them to try another brand.
^ Do not advise using a higher octane unleaded fuel than is recommended for that specific engine. Ford engines are designed to perform best using a high quality regular grade unleaded fuel.
^ Only advise using a higher octane unleaded fuel to avoid potentially damaging spark knock or ping, but do so only after mechanical fixes are ineffective.
NOTE: ALL UNLEADED GASOLINES USED SHOULD CONTAIN DETERGENT ADDITIVES THAT ARE ADVERTISED AS HAVING "KEEP CLEAN" OR "CLEAN UP" PERFORMANCE FOR BOTH INTAKE VALVES AND FUEL INJECTORS.

If my memory is serving me correctly, these distributor rods were part of either a possible TSB or a recall related to the early automatic equipped Mustang 5.0 having ping issues after shifting under hard acceleration. The answer to this was to install these rods instead of finding other, better ways to remedy the problem.
Personally, I think they are a answer to a question that was not really asked by anyone with half a brain. All anybody needed to do was back the initial timing back 2 to 3 degrees and test the vehicle for pinging under hard acceleration. Even the most basic backyard mechanic could figure that one out.
