I know there is an old post out there somewhere about this, but don't have the patience to go through everyone. Can anyone tell me what would be the best spark plug gap for the Ignitor I (I am also using the Flame thrower I). What difference does this have on the car?

I set mine at about .045; This is on a 66 w V8. IIRC the standard was about .035. I basically have the same pertronix setup.
This from what I remember is for a hotter spark and better efficiency.

will the difference in engines make a difference in what gap to use? Mine is a 351W 4bbl

What is your factory gap spec; do you know? From that I think you can add in the range of .005 to .01
