spark plugs
hey guys been wondering was at my local oreilly's the other day and saw that they had motorcraft platinum plugs available in stock for my 460 would you guys get those or just the autolite plugs. I have always just used the standard autolite plugs in everything

If you have a stock coil don't get the platinums. Harder to send the spark through platinum. If you have a "hot" coil then they would be ok. I'd stick with the standard Ford Motorcraft spark plugs. Of course I am a Ford Partsman..........................
Edit:
If any one wants the Ford Motorcraft spark plug part numbers for their application let me know.
Examples:
Big Plug.......(13/16" socket).........Usually standard heat range......suppressor plug for no radio noise.......BSF42C
big plug..........same.................... One heat range colder.............................same........... .....................BSF32C
Peanut plug..(5/8" socket)............usually standard heat range.....................same.................... ............ASF42C
Peanut plug..........same................One heat range colder.............................same........... .....................ASF32C

You are wasting your money on any of this hi-tech aftermarket crap. The opening of the points creates an electrical disaster in the secondary circuit. Something like 20,000 volts which causes the plug arc. The wire has a resistance of about 1,000 ohms. The plug electrode has a resistance of .01 ohm. Once the arc initiates, the cylinder fires.
