confused - or just a stupid question

I have a tach, but I can't remember where it was at. It's probably the gears. I do not have a sure grip. Just 2:76 and a 8 1/4. A couple other things can be causing this. The engine only had about 500miles on it, maybe it needs to be broken in more. But I think it will be resolved greatly when my timing gets to where it should be. Which I have been told should be between 30-34. That will happen this week. Then gears down the road. Putting a new convertor in is not an option. Not just the money part but the effort it will take. The transmission was just rebuilt with a stock replacement convertor and I can't pull everything out just for a new convertor. Like I said, gears will be easier and better in the end. Im looking forward to it! :headbang:
