1. Buy a Chilton's or Haynes manual for your car. Make sure it has the wiring diagrams as they can be very useful.


2. Follow the tune up directions and specifications in the manual.


3. When replacing the distributor cap/rotor always buy the ones with brass contacts. The aluminum contact caps/rotors do not last long and are usually cheaply made.


4. Ford Racing 8mm plug wires will work fine unless you have a high powered aftermarket ignition system.


5. Stick with the Autolite spark plugs. Most of the "gimmick" spark plugs are not worth carrying home.


6. Set your timing as shown in the manual. 10 degrees BTDC is the stock setting. You can advance it to 12 -16 degrees BTDC, but that may require you to run a higher octane fuel at the more advanced settings.
Advance the timing in 2 degree increments and test drive the car after each 2 degree increment advancement. If you hear it pinging, then back the timing off 2 degrees and leave it there. What you are hearing when it pings will be the engine detonating, which can destroy your engine if it is ran in that condition for very long.

I agree. But the only problem is a lot of time the local stores only carry Haynes.

Order online from Amazon.Occasionally you can find slightly used or new for less than you can get them local.
