Hard for me to believe too but I have the results documented over several tests I've run

Keep in mind, this is with the vac adv disconnected...

If your wanting to run 87 octane try restting the fan so you are at 160 deg. again. Also try a cooler plug. Here in the Midwest 91 octane is available most places. 93 octane and you have to know where to get it. So in my opinion 91 octane is pump gas. Also how much vac. advance do you have?

What happens when you spend the extra 10 cents a gallon and buy 89 octane? Does it still ping? Gas is lousy these days and ethanol is even worse. I even run mid grade in my Honda daily because that puts it where it likes to run best.

What happens when you spring for high test?

Hi People,
May I suggest that you set everything back to regulation timing etc
and use a different fuel depot for a few weeks...All the best..Skyeking

How do I determine which plug would be colder, aside from that, any suggestions on WHICH spark plug to run? (vortec head: 14mm tapered thread, 0.75" thread length)

Also how much vac. advance do you have?

As of last night I am running a total of 34* advance, 10* initial, 14* mechanical, 10* vacuum adv

Will do, just not sure who's data to follow, Carter or Edelbrock...
- Carter suggests 3/8" float level and 15/16" drop
- Edelbrock suggests 7/16" float level and 1-1/4" drop

Sage advice, nothing wrong with re-grounding ourselves every once in a while

I have keep pretty good notes with all the tuning I am doing and every so often I revert things back to a previous point to make sure I get the same old results, so far I do and not extra parts left over either!

Thanks for replies guys!
