Chad,

You were correct in assuming that I was talking "ignition" timing. I thought that ignition timing was dependent on what CAM you have installed. I may be mistaken? According to my Ford engine book, a stock 289 has timing set to 10 degrees BTDC.

So my question is,
1.) If I have an MSD-6A ignition/distributor setup and the above cam, does this change how my timing should be set? Compression is about 9.3:1 on the car.

2.) I've also been running 93 octane gas and noted that the plugs are becoming fowled. Perhaps I should only be using 87 octane based on my current timing?

3.) Plugs come pre-gapped for a 289 at .035". I was told that I should open the gap to .045" to reduce the fowling????

I wish there were a reference that dictated if you have this and this and that....set to this. etc......

Regards,
