TFI module replacement - quick question...

[Loco5.0]

As long as I mark the dist & base & then line the marks back up after I am done swapping the TFI module all should be well, right? Last thing I need is my timing screwed up.

YOu should not have to even pull the dizzy to replace the TFI.

If for some reason you do pull the dizzy....

Mark the base and the exact position of the rotor. Of course you'll want to put a light on it once you reinstall it.

Not going to pull it, just turn it to get to the rear bolt on the TFI module.

Yes -- should be fine (or close).

(or close) does not sound good.

the only way to get timing perfect to a given degree after moving the dizzy is with a timing light. that is what Adam meant (I think). however, if using a metal scribe one can get really close (and time it by ear, which is the most important part of setting timing, IMHO).

Exactly what I meant -- guess I could have worded it better.

Adam, i figured that was what you meant and i was in agreement with your thoughts. As an aside, I am not a huge fan of timing lights myself - the stang is the first car i ever used one on. i always used my ear (which i still have to, even with a light). But now I can tell people what advance i run.
