korvet: Motor is a pump gas 468 that started life as a merc 420. Prop dyno'd north of 500.
ez: sorry to hear about your o2 issues. I've gone over 30hrs now w/o issue. Last thing I did was use the Innovative motorsport o2 heat sink. Nice but pricy piece. Really shields the sensor and I noticed no difference in reading. I also setup the ecu so closed loop is now off up to 1500 rpm just in case I short another one I can limp home. If another one goes at this point I think I'll just eliminate the o2 altogether as I am really happy with the tune.

Tibbstoy2 - thank you for the kind words. She's still running strong and I've not changed much of anything since this write-up.....until probably this year when I look to upgrade to a crank triggered ignition (thank you for the information on that!) and go to V4 of the Holley software to take advantage of some of the new features they have added.
