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

Next tank full will be high test, I will post results

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!
