I was waiting for this........Conventional wisdom.... ( as Superman often says here) etc.,etc., etc.

Of course, I monitored engine temps carefully after retarding the timing 5 degrees. There is *no* apparent increase in engine temps. I know how the gauge on my car responds to various driving conditions, there was no change, so I have no concerns about overheating. Nor does my pro-mechanic.
