Re: Timing & Gas Milage

-what is the diameter of your tires?
-does your starter turn slower when the engine is hot vs cold start? (ie engine is tight)
-do you have excessive "slippage" of your torque converter (assuming it is a non lock up?)
That makes some sense, though I don't think I went wrong getting a different distributor that didn't come from eBay that no one seems to have heard of before.
  1. 275 60 15
  2. Not at all. My starter has no problems, turns over well (cold or hot).
  3. All I know it is a stock TH350 that was overhauled when the engine was done.

Sorry, I cannot say either way - need to find out what wideband means.

Good luck.
Noted, though sounds complicated! I need to print that out, read over it to insure I understand what you have suggested. Personally, I have all the time in the word to try things out at least once! Though to remember @cj847 comment, perhaps I need to let it break in a bit more...
